13 p, 1.2 MB Integrability Properties of the Slepyan-Palmov Model Arising in the Slepyan-Palmov Medium / Usman, Muhammad (National University of Sciences and Technology. College of Electrical and Mechanical Engineering) ; Hussain, Akhtar (Government College University. Abdus Salam School of Mathematical Sciences) ; Zaman, Fiazuddin (Government College University. Abdus Salam School of Mathematical Sciences) ; Ibeas, Asier (Universitat Autònoma de Barcelona. Departament de Telecomunicació i Enginyeria de Sistemes) ; Almalki, Yahya (King Khalid University. Department of Mathematics)
This study investigates the Slepyan-Palmov (SP) model, which describes plane longitudinal waves propagating within a medium comprising a carrier medium and nonlinear oscillators. The primary objective is to analyze the integrability properties of this model. [...]

29 p, 508.5 KB Simplicial Lusternik-Schnirelmann category / Fernandez-Ternero, Desamparados (Universidad de Sevilla. Departamento de Geometría y Topología) ; Macías-Virgós, Enrique (Universidade de Santiago de Compostela. Departamento de Matemáticas) ; Minuz, Erica (Aarhus University (Dinamarca). Department of Mathematics) ; Vilches Alarcón, José Antonio (Universidad de Sevilla. Departamento de Geometría y Topología)
The simplicial LS-category of a finite abstract simplicial complex is a new invariant of the strong homotopy type, defined in purely combinatorial terms. We prove that it generalizes to arbitrary simplicial complexes the well known notion of arboricity of a graph, and that it allows to develop many notions and results of algebraic topology which are costumary in the classical theory of Lusternik-Schnirelmann category. [...]

30 p, 475.3 KB Sullivan minimal models of operad algebras / Cirici, Joana (Universität Münster. Fachbereich Mathematik und Informatik) ; Roig, Agustí (Universitat Politècnica de Catalunya. Departament de Matemàtiques)
We prove the existence of Sullivan minimal models of operad algebras for a quite wide family of operads in the category of complexes of vector spacesover a field of characteristic zero. Our construction is an adaptation of Sullivan's original step by step construction to the setting of operad algebras. [...]

We establish an algebraic version of the classical result that a G-map f between G-complexes which restricts to a homotopy equivalence fH on H-xed sets for all subgroups H of G is a G-ho-motopy equivalence. [...]

14 p, 613.4 KB Parametrizations of Kojima's system and relations to penalty and barrier functions / Kummer, Bernd
We investigate two homotopies that perturb Kojima's system for describing critical points of a nonlinear optimization problem in finite dimension. Each of them characterizes stationary points of a usual penalty and a new "barrier" function. [...]

16 p, 974.1 KB Implementation of a continuation method for normal maps / Sellami, Hichem ; Robinson, Stephen M.
This paper presents an implementation of a nonsmooth continuation method of which the idea was originally put forward by Alexander et al. We show how the method can be computationally implemented and present numerical results for variational inequality problems in up to 96 variables. [...]

Dado un espacio topológico punteado A, E. Dror-Farjoun introduce en 1995 la noción de A-homotopía, donde A y sus suspensiones juegan el mismo papel que las esferas en homotopía clásica. Por tanto se definen los grupos de A-homotopía de un espacio punteado X como las clases de homotopía de aplicaciones definidas desde las suspensiones de A a X. [...]
Given a pointed topological space A, in 1995 E. Dror-Farjoun introduced the notion of A-homotopy, where A and its suspensions play the same role of the spheres in classical homotopy. Therefore the A-homotopy groups of a pointed space X are defined as the homotopy classes of maps from the suspensions of A to X. [...]
