Uma classe de problemas de Dirichlet do tipo p(x)-laplaciano
(Universidade Federal de Santa Maria, 2019-04-11)
We study the following class of PDEs of 𝑝�(𝑥�)-laplacian type
﹛−div (︂𝜑�(𝑥�, |∇𝑢�|)∇𝑢�)︂ = 𝜆�𝑓�(𝑥�, 𝑢�), if 𝑥� ∈ Ω
𝑢�(𝑥�) = 0, if 𝑥� ∈ 𝜕�Ω,
where Ω ⊂ R𝑁� is a bounded domain with a Lipschitz boundary ...

Modelos discretos para dinâmica hospedeiro-parasitoide-predador
(Universidade Federal de Santa Maria, 2019-10-17)
In this work, we formulate discrete models, described by Difference Equations and Coupled
Map Lattices, in order to analize the local and spatio-temporal dynamics of hostparasitoid-
predator dynamics. We firstly consider ...
