We consider the following classical problem of interpolation theory: Let Ā = (A0,A1), B̄ = (B0,B1) be a Banach couples, let T : A0 → B0 be compact and T : A1 → B1 be bounded; when is T : Ā[θ] → B̄[θ] ...
Fournier and Printems [Bernoulli 16 (2010) 343-360] have recently established a methodology which allows to prove the absolute continuity of the law of the solution of some stochastic equations with ...
Barycentric coordinates provide a robust framework for expressing any point within a simplex—typically a triangle or convex polygon—as an affine combination of its vertices. This representation has ...
La théorie de l'interpolation des espaces vectoriels a débuté par une observation faite par Józef Marcinkiewicz, et qui fut généralisée ultérieurement et connue sous le non de Théorème de Riesz-Thorin ...
