On Some Boundedness and Convergence Properties of a Class of Switching Maps in Probabilistic Metric Spaces with Applications to Switched Dynamic Systems / De la Sen, Manuel (Universidad del País Vasco. Departamento de Electricidad y Electrónica) ; Ibeas, Asier (Universitat Autònoma de Barcelona. Departament de Telecomunicació i Enginyeria de Sistemes)
This paper investigates some boundedness and convergence properties of sequences which are generated iteratively through switched mappings defined on probabilistic metric spaces as well as conditions of existence and uniqueness of fixed points. [...]

Non-existence and uniqueness of limit cycles for planar polynomial differential systems with homogeneous nonlinearities / Huang, Jianfeng (Jinan University. Department of Mathematics) ; Liang, Haihua (Guangdong Polytechnic Normal University. School of Mathematics and Systems Science) ; Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
In this paper we study the limit cycles of the planar polynomial differential systems * x=ax-y P_n(x,y),\\ y=x ay Q_n(x,y), * where P_n and Q_n are homogeneous polynomials of degree n2, and a R. Consider the functions * &()=P_n() Q_n()\\ &()=Q_n()-P_n()\\ &_1()=a()-(),\\ &_2()=(n-1)(2a()-()) '(). [...]

Existence and uniqueness of limit cycles for generalized -Laplacian Liénard equations / Pérez-González, Set (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Torregrosa, Joan (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Torres, Pedro J. (Universidad de Granada. Departamento de Matemática Aplicada)
The Liénard equation x'' + f(x)x' + g(x) = 0 appears as a model in many problems of science and engineering. Since the first half of the 20th century, many papers have appeared providing existence and uniqueness conditions for limit cycles of Li'enard equations. [...]

$A duality approach to the fractional Laplacian with measure data$

11 p, 301.6 KB

A duality approach to the fractional Laplacian with measure data / Karlsen, Kenneth H. (University of Oslo. Centre of Mathematics for Applications) ; Petitta, Francesco (Universitat de València. Departament d'Anàlisi Matemàtica) ; Ulusoy, Suleyman (University of Maryland. Center for Scientific Computation and Mathematical Modeling)
We describe a duality method to prove both existence and uniqueness of solutions to nonlocal problems like (-∆)s ʋ = µ in RN with vanishing conditions at inffnity. Here if is a bounded Radon measure whose support is compactly contained in RN N ≥ 2, and - (∆)s is the fractional Laplace operator of order s ϵ (1/2,1).

Convergence of an entropic semi-discretization for nonlinear Fokker-Planck equations in Rd / Carrillo de la Plata, José Antonio (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Gualdani, Maria P (University of Texas at Austin. Department of Mathematics) ; Jüngel, A. (Technische Universität Wien (Alemanya). Institut für Analysis und Scientiﬁc Computing)
A nonlinear degenerate Fokker-Planck equation in the whole space is analyzed. The existence of solutions to the corresponding implicit Euler scheme is proved, and it is shown that the semi-discrete solution converges to a solution of the continuous problem. [...]

Definiteness, indefiniteness and short weak definites : Reference to kinds and kinds of events / Bacari López, Majula ; Espinal, M. Teresa, (Maria Teresa) dir. ; Universitat Autònoma de Barcelona. Facultat de Filosofia i Lletres
The purpose of this study is to analyze in which way weak definites differ from indefinites in terms of the assumption of both uniqueness and existence and what are the requirements (i. e. , lexical and verbal restrictions) that a definite expression in combination with a verb has to satisfy to be able to convey a weak reading. [...]
La finalitat d'aquest estudi és analitzar en què es diferencien els definits febles dels indefinits quant a l'assumpció tant de la unicitat com de l'existència i quins són els requisits (i. e. , les restriccions lèxiques i verbals) que ha de satisfer una expressió definida en combinació amb un verb per poder transmetre una lectura feble. [...]
El propósito de este estudio es analizar en qué se diferencian los definidos débiles de los indefinidos en cuanto a la asunción tanto de unicidad como de existencia y cuáles son los requisitos (i. [...]
