Pseudogap e energia cinética de supercondutores não convencionais descritos por um modelo de Hubbard em duas dimensões
(Universidade Federal de Santa Maria, 2020-03-30)
In conventional superconductors described by the Bardeen-Cooper-Schrieffer (BCS) Theory,
the transition from the normal to the superconducting state is accompanied by a reduction
in the potential energy and an increase ...
Existência e regularidade de soluções fundamentais para operadores diferenciais lineares de coeficientes constantes
(Universidade Federal de Santa Maria, 2020-03-19)
The main objective of this dissertation is to present a theorem that guarantees the existence
and regularity of fundamental solutions for linear differential operators with constant
coefficients. We also present some of ...

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 ...
Explorando os conceitos de elemento neutro e oposto por meio da resolução de equações no conjunto dos números racionais
(Universidade Federal de Santa Maria, 2020-07-03)
In this work we presented an activity proposal that contemplates an adaptation of the definition
of ring for Elementary School, with the objective of understanding the concepts and
operational properties studied at this ...
Transformações geométricas e matrizes: uma proposta de ensino com base na sala de aula invertida
(Universidade Federal de Santa Maria, 2020-09-25)
The objective of this work is to present a teaching proposal through a didactic
sequence on the study of geometric transformations and their representation through
matrices. For this, we adopted the active methodology ...
Estudo experimental de recursos quânticos usando os computadores quânticos da IBM
(Universidade Federal de Santa Maria, 2021-02-26)
Bell-diagonal states are extremely important for understanding the dynamics and applications
of some quantum resources. Quantum properties such as steering, entanglement,
and coherence, among others, can be used as ...
Dinâmica de redes genéticas regulatórias do destino celular em resposta a dano ao dna contemplando senescência, autofagia e apoptose
(Universidade Federal de Santa Maria, 2021-03-24)
How a cell determines a given phenotype upon damaged DNA is an open problem. Cell
fate decisions happen at cell cycle checkpoints and it is becoming clearer that the p53
pathway is a major regulator of cell fate decisions ...
Redes neurais profundas na computação de heurísticas para algoritmos de busca de caminhos em mapas virtuais contendo elevação e inclinação
(Universidade Federal de Santa Maria, 2021-02-09)
Deep neural networks and pathfinding algorithms have been investigated in the area of
Artificial Intelligence (AI). Despite this, these areas of research still require greater integration,
mainly with a view to proposing ...
