Um estudo sobre o teorema de Àrzela-Ascoli
(Universidade Tecnológica Federal do ParanáToledoBrasilLicenciatura em MatemáticaUTFPR, 2016-06-24)
The aim of this paper is to conduct a study about sequences and series of functions, in which the main types of convergence are analyzed. It is also proved the following theorem due to Arzela-Ascoli: Given ffngn, equicontinuous ...

Some existence results for variational inequalities with nonlocal fractional operators
(2019-12-01)
In this paper we consider the following nonlocal fractional variational inequality u∈X0 s(Ω),u⩽ψa.e. in Ω,〈u,v−u〉X0 s(Ω)−λ〈u,v−u〉2⩾∫Ωfx,u(x),(−Δ)βu(x)(v(x)−u(x))dxaaaaaaaaaaaaaaaaaaaaaaaaaaaaafor anyv∈X0 s(Ω),v⩽ψa.e. in ...
Bound states for the quantum dipole moment in two dimensions
(IOP Publishing, 2012-11-16)
We calculate accurate eigenvalues and eigenfunctions of the Schrodinger equation for a ¨ two-dimensional quantum dipole. This model proved useful for the study of elastic effects of a single edge dislocation. We show that ...
A Variational Approach to the Control of Electrochemical Hydrogen Reactions
(Elsevier, 2005-12)
The optimal control problem for the hydrogen evolution reaction (HER) system is posed for different cost objectives and admissible control strategies. The solution for the set-point-change process is given in analytical ...
MaxEnt, second variation, and generalized statistics
(Elsevier Science, 2015-06)
There are two kinds of Tsallis-probability distributions: heavy tail ones and compact support distributions. We show here, by appeal to functional analysis' tools, that for lower bound Hamiltonians, the second variation's ...

Simetria e quebra de simetria para problemas do tipo Hénon envolvendo o operador 1-Laplaciano
(Universidade Estadual Paulista (Unesp), 2021-06-09)
Neste trabalho, estudamos uma classe de equações do tipo Hénon que envolvem o operador 1-Laplaciano na bola unitária. Com algumas condições sobre a não-linearidade, prova-se a existência de soluções radiais e, para um ...
Restrições de estabilidade no controlador preditivo robusto baseado em modelo
(Universidade Federal de Minas GeraisUFMG, 2015-12-17)
Model Predictive Control (MPC) is a modern control technique that has several variations and many applications in industry. A new robust MPC strategy - RMPC-SC (Robust MPC with Stability Constraints) - is proposed in this ...
On the regularization of mixed complementarity problems
(2000-12-01)
A variational inequality problem (VIP) satisfying a constraint qualification can be reduced to a mixed complementarity problem (MCP). Monotonicity of the VIP implies that the MCP is also monotone. Introducing regularizing ...
