  • Formal Definition of the Concept “Infos”

    The concept INFOS is very important for understanding the information phenomena. Because of this, it is basic for the General Information Theory. The more precise formal definition of this concept is given in the paper.

    Generalized Variational Inequalities for Upper Hemicontinuous and Demi Operators with Applications to Fixed Point Theorems in Hilbert Spaces

    ∗ The final version of this paper was sent to the editor when the author was supported by an ARC Small Grant of Dr. E. Tarafdar. Existence theorems of generalized variational inequalities and generalized complementarity problems are obtained in topological vector spaces for demi operators which are upper hemicontinuous along line segments in a convex set X. Fixed point theorems are also given in Hilbert spaces for set-valued operators T which are upper hemicontinuous along ...

    Ontological Multilevel Modeling Language

    This paper presents ontological multilevel modeling language O2ML, aimed at using with metadata driven information systems. The first part of this paper briefly surveys existing modeling languages and approaches, while the last part proposes a new language to combine their benefits.

    Характеристични свойства на някои многостени

    Plamen Penchev - The origin is a problem from the Canadian Mathematical Olympiad in 1980, which is solved in general and ended to similar variants. Certain characteristic properties of such polyhedra are investigated. През 1980 г. на олимпиадата в Канада беше предложена следната задача: Паралелепипедът има следното свойство: произволно сечение, успоредно на негова стена, има периметър P равен на периметъра на тази стена. Съществуват ли други изпъкнали многостени с това свойств...

    Fibrés Vectoriels Semi-Stables sur une Courbe de Genre Deux et Association des Points dans L’espace Projectif

    2000 Mathematics Subject Classification: 14D20, 14J60. The aim of this paper is to prove that a certain involution on the moduli space of stable bundles on a curve of genus two, can be viewed as a geometric operation on the corresponding set of points in projective space.
