NUMERICAL QUENCHING FOR A SEMILINEAR PARABOLIC EQUATION WITH A POTENTIAL AND GENERAL NONLINEARITIES
(Universidad Católica del Norte, Departamento de Matemáticas, 2008)
Patterns in parabolic problems with nonlinear boundary conditions
(Elsevier B.V., 2014)
Semilinear parabolic problems in thin domains with a highly oscillatory boundary
(Pergamon-Elsevier B.V. Ltd, 2013)
Optimal control of parabolic equations by spectral decomposition
(2017)
This paper deals with an optimal control problem of Bolza type for a class of parabolic equations. It consists in finding the initial datum that minimizes a cost functional, which comprises an energy term on the control ...
Non-autonomous semilinear evolution equations with almost sectorial operators
(BIRKHAUSER VERLAG AG, 2008)
Inspired by the theory of semigroups of growth a, we construct an evolution process of growth alpha. The abstract theory is applied to study semilinear singular non-autonomous parabolic problems. We prove that. under natural ...
Analysis of Backward Euler Primal DPG Methods
(2021)
We analyze backward Euler time stepping schemes for a primal DPG formulation of a class of parabolic problems. Optimal error estimates are shown in a natural norm and in the L-2 norm of the field variable. For the heat ...
Generalized solutions of the Cauchy problem for the Navier-Stokes system and diffusion processes
(Universidad de La Frontera. Departamento de Matemática y EstadísticaUniversidade Federal de Pernambuco. Departamento de Matemática, 2010)
Global–Local ROM for the solution of parabolic problems with highly concentrated moving sources
(Elsevier Science Sa, 2017-11)
Problems characterised by steep moving gradients are challenging for any numerical technique and even more for the successful formulation of Reduced Order Models (ROMs). The aim of this work is to study the numerical ...
Preconditioning a class of fourth order problems by operator splitting
(Springer, 2010-09)
We develop preconditioners for systems arising from finite element discretizations of parabolic problems which are fourth order in space. We consider boundary conditions which yield a natural splitting of the discretized ...
