The present work shows Cauchy's Theorem on its classical form, and it has the objective of weakening their statements, and provides aplications in continuum mechanics. The metodology used here is the axiomatic, that is, a ...

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, 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 ...

In this work, we present the concepts of loop transversal, centralizer ring and S-ring over a permutation group. The connection between these three subjects was obtained by Kenneth W. Johnson, where he translated the results ...

Some Hopf algebras braided in the Yetter-Drinfeld modules category have an important role in the classification of pointed Hopf algebras. Our main goal in this work will be to characterize braided Hopf algebras in ...

In this work, discrete mathematical models are proposed to analyze the dynamics of a population of howler monkeys stricken with periodic outbreaks of yellow fever. Using the cellular automata framework, the models describe ...

This study aims to determine the eigenfunctions or vibration modes of a system composed of two beams coupled by an elastic layer and modeled mathematically by Timoshenko theory for beams. The study is conducted through ...

In this work, we present some results of Qualitative Theory of Planar Ordinary Differential Equations employed in the investigation of the behavior of solutions in the neighborhood of semi-hyperbolic and nilpotent singularities.

In this dissertation, we present results on the existence of limit cycles in planar differential systems, configuration of such cycles and the dynamics of nonlinear systems near periodic orbits.

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 ...
