On the solution of mathematical programming problems with equilibrium constraints
(2002-02-01)
Mathematical programming problems with equilibrium constraints (MPEC) are nonlinear programming problems where the constraints have a form that is analogous to first-order optimality conditions of constrained optimization. ...
Conservation laws for non-potential operators
(1999-12-01)
A study was developed in order to build a function M invariant in time, by means of Hamiltonian's formulation, taking into account the equation associated to the problem, showing that starting from this function the equation ...
Ordered phases in the extended Hubbard model
(Elsevier B.V., 1994-04-02)
A novel method to probe the diverse phases for the extended Hubbard model (EHM), including the correlated hopping term, is presented. We extend an effective medium approach [1] to a bipartite lattice, allowing for charge- ...
Basic ingredients for mathematical modeling of tumor growth in vitro: Cooperative effects and search for space
(2013-11-01)
Based on the literature data from HT-29 cell monolayers, we develop a model for its growth, analogous to an epidemic model, mixing local and global interactions. First, we propose and solve a deterministic equation for the ...

Application of the Refined Integral Method in the mathematical modeling of drug delivery from onelayer torus-shaped devices
(Elsevier Science, 2012-02)
A mathematical modeling of controlled release of drug from one-layer torus-shaped devices is presented. Analytical solutions based on Refined Integral Method (RIM) are derived. The validity and utility of the model are ...

Quanto de Inusitado Guarda uma Sala de Aula de Matemática? Aprendizagens e erro
(2016-12-01)
A mathematics class in a public school: a usual school, a usual classroom. Everything flows as normal. However, an accurate attention to a small and trivial situation may constitute a watchful eye to simplicities in this ...
A Characterisation of the Centre for Mathematics Education (Centro de Educacao Matematica - CEM), 1984-1997, as a Community of Practice for the Professional Development of Mathematics Teachers
(Unesp-dept Mathematica, 2010-01-01)
This paper presents some results of a study on the Centre for Mathematics Education (Centro de Educacao Matematica, CEM), a group of mathematics educators from the city of Sao Paulo-SP (Brazil), active mainly during the ...
