Complementary inductive invariants and dimension
This is an exposition of a general machinery developed by M. G. Eastwood, T. N. Bailey, C. R. Graham which analyses some real integral transforms using complex methods. The machinery deals with double fibrations complex manifold; totally real, real-analytic submanifold;...
This contribution shows how to compute upper bounds of the optimal constant in Friedrichs’ and similar inequalities. The approach is based on the method of [9]. However, this method requires trial and test functions with continuous second derivatives. We show how to avoid this requirement and how to compute the bounds on Friedrichs’ constant using standard finite element methods. This approach is quite general and allows variable coefficients and mixed boundary conditions. We use the computed...
A l'occasion du bicentenaire de la mort de Condordet, nous rappelons la théorie du motif de croire du fondateur de la Mathématique sociale, théorie qui seule peut nous assurer de la «réalité» des vérités auxquelles nous conduit le calcul des probabilités , comme de toute autre espèce de vérités, s'il s'en trouve.
