This monograph begins with some of the basic physical ideas used in introducing a generalization of the groups. Properties of completely simple semigroups from algebraic, and topological viewpoints are studied. Genetic space as an example of topological completely simple semigroups is presented. A generalization of Lie groups by introducing Top spaces is considered. The concept of left invariant vector fields on Top spaces is introduced and then used to deduce a method for constructing new Lie algebras. By introducing generalized vector fields new dynamics with time values of evolution operators in completely simple semigroups is deduced. Generalized rings and quasi-modules as generalizations of rings and modules are studied. Finally the notion of tensors is extended to quasi-modules. The basic thoughts for further research based on completely simple semigroups are prepared.

Stability of Functional Equations of
Ulam-Hyers-Rassias Type

Edited by Stefan Czerwik

July 2003, ISBN 1-57485-057-1, pp. 200, hardcover, US$85,
softcover US$70

Stefan Czerwik received his Ph.D. in Mathematics from Jagiellonian University in Krakow in 1971. He has obtained the D.Sc. degree in Mathematics from Silesian University in Katowice in 1983. He is currently Professor of Mathematics in the Silesian University of Technology in Gliwice, Poland. Professor Czerwik is the author of the research book entitled "Functional Equations in Inequalities in Several Variables" published by World Scientific Publishing, 2002. He has published numerous research papers in functional equations, differential equations, fixed point theory, set-value mappings and applications, which have appeared in several international journals. The volume is devoted to the study of the problem of stability of functional equations of several variables. This problem had originally been posed by Stanislaw M. Ulam in 1940. One year later, Donald H. Hyers gave a significant partial solution to this problem. Thirty seven years later Themistocles M. Rassias provided a remarkable generalization of Hyers' result, a fact which rekindled interest in the field. Taking this fact into consideration, the Hyers-Ulam stability can therefore be called the Hyers-Ulam-Rassias stability. During the last decade several results for the Hyers-Ulam-Rassias stability of functional equations have been proved by several researchers worldwide. The volume is dedicated to the Twenty Fifth anniversary of the publication of this result of Rassias, which has provided a lot of influence in the development of the stability of functional equations.

Costantin Caratheodory in His...Origins

Proceedings of the International Congress, Vissa - Orestiada, Greece

Edited by Thomas Vougiouklis, Democritus University of Thrace, Greece

September 1-4, 2000, ISBN 1-57485-053-g, pp. 216, hardcover, US$85, softcover US$70

There are certain moments for concentration and evaluation, such as anniversaries in order that tribute should be paid to the pioneers' memory. For this reason, fifty years after the death of C. Caratheothory, it was organized at the International Congress "Constantin Caratheothory in his... Origins," in Vissa and Orestiada, Greece, from 1 to 4 September 2000. In the captivating countryside, by the primeval river Evros, and in an emotionally charged atmosphere, in Constantin Caratheothory's Origins, there were presented a number of original scientific papers on both research areas Caratheothory had worked on, as well as about himself as a historical personage. These proceedings include four invited lecturers as well as a selection of fifteen papers presented in the Congress after being refereed. Thus the Scientific Committee express their thanks to the referees for their contribution.

Fractal Dimensions and Dynamical Systems

Xenofon S. Motsenigos, University of Warwick, Coventry, UK

February 2001, ISBN 1-57485-052-0, pp. 115, hardcover, US$65

One of the problems of interest in Dynamical Systems is the determination of the asymptotic behaviour of orbits. Often, we are required to find ways to describe various complicated sets (like attractors or basins of attraction for example) that are strongly related to this asymptotic behaviour problem. The aim of this book is to introduce fractal dimensions (Box-counting and Hausdorff dimensions in particular) as a tool which aids in the description and understanding of these complicated sets and, therefore, of the related dynamics.

Hyers-Ulam-Rassias Stability of Functional Equations in
Mathematical Analysis

SOON-MO JUNG, College of Science and Technology, Hong-Ik University, Korea

Monograph in Mathematics
February 2001, ISBN 1-57485-051-2, pp. 260, hardcover, US $ 85

The study of stability problems for various functional equations originated from a famous talk given by Stanislaw M. Ulam in 1940. In the talk, Ulam discussed a number of important unsolved mathematical problems. One of them was a question concerning the stability of homomorphisms. In the following year, 1941, Donald H. Hyers gave a partial solution to Ulam's question. This was the first signifant breakthrough in this area. After D. H. Hyers gave an affirmative answer to Ulam's question, a large number of papers have been published in connection with various generalizations of Ulam's problem and Hyer's theorem. In particular, Themistocles M. Rassias succeeded in extending the result of Hyer's theorem by weakening the condition for the Cauchy difference. This remarkable result of Rassias directed the concern of mathematicians towards the study of stability problems of functional equations. Unfortunately, there were no books that gave a comprehensive illustration of the fast developing field of nonlinear analysis to the mathematicians who were interested in this field for more than a half century until D. H. Hyers, G. Isac and Th. M. Rassias published their book, "Stability of Functional Equations in Several Variables." The present book will complement the book of Hyers, Isac and Rassias by presenting mainly the results concerning the Hyers-Ulam-Rassias stability. The concept of the Hyers-Ulam-Rassias stability is a generalization of the Hyers-Ulam stability of functional equations. The subjects on the Hyers-Ulam-Rassias stability have been extensively investigated by many mathematicians. This book covers almost all classical results on the Hyers-Ulam-Rassias stability in an integrated and self-contained fashion.

Interactions, Strings and Isotopies in Higher Order Anisotropic Superspaces

SERGIU ION VACARU, Academy of Sciences of Moldova, Republic of Moldova and
The Institute for Basic Research, U.S.A.

Dec. 1998, ISBN 1-57485-032-6, pp. 450, US$85

This is the first monograph on the geometry of locally anisotropic physics. The main subjects are the theory of field interactions, strings and diffusion processes on spaces, superspaces and isospaces with higher order anisotropy and inhomogeneity. The approach proceeds by developing the concept of higher order anisotropic (super)space which unify the logical and mathematical aspects of modern Kaluza-Klein theories and generalized Lagrange and Finsler geometry and leads to modelling of physical processes on higher order fiber (super) bundles provided with nonlinear and distinguished connections and metric structures. The view adopted is that a general field theory should incorporate all possible anisotropic and stochastic manifestations of classical and quantum interactions, and, in consequence, a corresponding modification of basic principles and mathematical methods in formulation of physical theories. This book can be also considered as a pedagogical survey on the mentioned subjects.

The Institute for Basic Research, Italy and U.S.A.

1998, ISBN 1-57485-033-4, pp. 230, US$65

The Miron's monograph is devoted to the geometry of higher-order Finsler spaces F(k)n. Whole of his theory is based on the fundamental ideas from the higher order Lagrangian dynamics. Therefore in this book are studied: Variational problems for the Lagrangians of higher order, Lagrange equations, Noether theorems, Jacobi-Ostrogradski momenta,Hamilton-Jacobi equations, higfher order energies, laws of conservation, canonical k-spray, nonlinear connection, linear connections and them structure equations, the geometrical model of a higher order Finsler space and a theory of subspaces. Here appear, for the firat time a correct definition of the notion of higher order Finsler space and a systematical study of its geometry. Also, is given the solution of the famous problem of prolongation of Riemann spaces to the jet bundle of higher order and the same problem for the prolongation of the Finsler spaces. In this way one obtains the most interesting examples of higher order Finsler spaces, extremlly useful in the construction of geometrical models for theoretical physics, higher order analytical mechanics, engineering, biology etc.

Hyperstructures and their Representations

T. VOUGIOUKLIS (Democritus Univ. of Thrace, Greece)

1994, ISBN 0-91176-86-X, 190 pages, $ 65

This book deals with the advanced field of mathematics known as classical algebraic hyper-structures (or multivalued algebras) with at least one hyperoperation (multivalued operation), and includes semihypergroups, hypergroups, hyperrings, hyperfields, hypermatrices, etc., with further generalizations in which the conventional axioms of associativity, commutativity and distributivity are replaced by the weak ones. The main topic of this book is the study of the representations of hypergroups via generalized permutations and hypermatrices. The main tools used in the study are the smallest equivalence relations in hyperstructures under which the quotient yields a corresponding structure. Several new classes of hyperstructures are introduced, such as the very thin hyperstructures, the P-hyperstructures, and others. The content of this book has direct applications in various branches of mathematics, including combinatorics, field theory, finite geometry, cryptography, computer science, etc. This book is highly recommended to pure and applied mathematicians and graduate students in mathematics.
