Adaptive discontinuous Galerkin approximations to fourth order parabolic problems [PDF]
, 2013 An adaptive algorithm, based on residual type a posteriori indicators of errors measured in $L^{\infty}(L^2)$ and $L^2(L^2)$ norms, for a numerical scheme consisting of implicit Euler method in time and discontinuous Galerkin method in space for linear ...

Mathematical Modelling and Analysis, 2002 We consider linear ill‐posed problems Au = ƒ with minimum‐norm solution u*. Instead of ƒ noisy data ƒδ are given satisfying ‖ƒδ — ƒ‖ ≤ δ with known noise level 5.

Functional a posteriori error estimates for parabolic time-periodic boundary value problems [PDF]
, 2014 The paper is concerned with parabolic time-periodic boundary value problems which are of theoretical interest and arise in different practical applications. The multiharmonic finite element method is well adapted to this class of parabolic problems.

Do testemunho à memória: o a posteriori entre a história e as ruínas
Diversitas: Perspectivas en Psicología, 2012 Basado en investigación bibliográfica, este trabajo analiza las relaciones entre testimonio y memoria de Giorgio Agamben, Sigmund Freud, Walter Benjamin y verifica el lugar, en esas relaciones, de las nociones de olvido, de restos, de ruinas y el a ...

Modal Empiricism and Two-Dimensional Semantics [PDF]
, 2009 In the paper I argue that it follows from David Chalmers’ semantics and metaphysics concerning microphysical terms that microphysical identifications are strongly necessary.

La dimensión empírica de la argumentación metafísica en Tomás de Aquino y Aristóteles
Tópicos, 2013 The author intends to evidence how demonstrations, as used by Aristotle and St. Thomas, do not resemble the ordinary mathematical demonstrations. Because demonstrations in Aristotle and Aquinas's metaphysics, are preferentially a posteriori by efficient ...
