In this work, we investigate the pattern formation of a reaction-diffusion generalist predator-prey system with constant alternative food source and a Holling type III functional response. The local model can exhibit up ...

In this work, we study existence and non existence for the Dirichlet problem for the minimal graph equation in non convex domains of the plane. We search for conditions on the boundary data which be the less restricted ...

In this paper, we present numerical results obtained from the FORTRAN language for physical quantities of interest such as velocity profile, pro�le, heat ow rate, particle ow rate,heat ux and pressure tensor component. The ...

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, ...

Based on the articles Associativity of crossed produts by partial actions, enveloping actions and partial representations" of M. Dokuchaev and R. Exel ([7] and Enveloping Actions for Partial Hopf Actions" of M.M.S. Alves ...

The method discrete ordinates is used to solve problems involving rarefied gas dynamics. In this work, a version of the analytical method discrete ordinates (ADO) is used to solve problems in a semi-infinite. The complete ...

In this thesis we present a proof of the Malgrange-Ehrenpreis theorem, which states that every operator with constant coefficients non identically zero has a fundamental solution.

This work presents the Cauchy's theorem in its classical form, and aims to weaken their hypotheses, providing a more advantageous use in continuum mechanics. The methodology is axiomatic, that is, basic concepts are ...

This paper presents a methodology for determining eigenfunctions and frequencies of the Euler-Bernoulli model for elastic beams that can include damping and devices located at intermediate or end points of the beam. The ...

In this work we studing a generalized predator-prey system in a spatial domain, in terms of formation. We show parameter, regions where transcritical, Hopf and Turing bifurcations appear are presented, and also some ...
