37 p, 677.7 KB Some open problems in low dimensional dynamical systems / Gasull, Armengol (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
The aim of this paper is to share with the mathematical community a list of 33 problems that I have found along the years in my research. I believe that it is worth to think about them and, hopefully, solve some of the problems or make some substantial progress. [...]

18 p, 797.8 KB Limit cycles for m-piecewise discontinuous polynomial Liénard differential equations / Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Teixeira, Marco Antonio (Universidade Estadual de Campinas(Brazil). Departamento de Matemática)
We provide lower bounds for the maximum number of limit cycles for the m-piecewise discontinuous polynomial differential equations x = y + sgn(gm (x, y))F (x), y = −x, where the zero set of the function sgn(gm (x, y)) with m = 2, 4, 6, . [...]
