In this work we study the classical results of existence and non-existence of solutions for the Dirichlet problem for the minimal hypersurfaces equation in bounded domains of Rn due to Jenkins-Serrin [8].

The main purpose of this dissertation is to propose and analyze the effects of pursuit and evasion on predator-prey spatiotemporal dynamics. We use a Coupled Map Lattices formulation in which a system of difference equations ...

In this work we presented some existence results about constant mean curvature surfaces in R³ with prescribed boundary in parallel planes, topologically an annulus, that are obtained by solving Dirichlet s problems for ...

The main purpose of this dissertation was to analyze the occurrence of two time scales in predator-prey systems. Initially, we proposed two discrete models without spatial structure. The first model considers fast vital ...

In this work, based on the Law of conservation of mass and the Newton s second Law, we deducted the equations of Navier-Stokes for the uncompressing fluids. Then we have developed in a detailed way the varying form of ...

Mark V. Lawson, in the book "Inverse Semigroups: The Theory of partial symmetries", provides a very relevant study of the characteristics of inverse semigroups, including Wagner-Preston Theorem of Representation, ...
