Bordo assintótico de superfícies mínimas em H2 × R
(Universidade Federal de Santa Maria, 2020-02-27)
In this work, we present some examples of minimal surfaces in H2 × R, and also a description
of the product and geodesic boundary of these surfaces. Our main goal is to
prove Theorem 5.1 of the Kloeckner and Mazzeo’s ...
Sistemas magnéticos com interações competitivas: uma abordagem de campo médio com clusters
(Universidade Federal de Santa Maria, 2020-04-27)
We study a model of localized spins which can assume three different states, S = 0 and
1, with two competing interactions: a antiferromagnetic first neighbour interaction (JA)
and a three body interaction between third ...
