2 Limited operators and differentiability

The origin of this paper is the following natural question: Given two Banach spaces B and E, is it possible to describe all the operators from B to E that can be extended to

Conversely, it is easy to check that the latter condition implies that T a is bounded.. Moreover Λ is composed of eigenvalues λ associated with finite dimensional vector

But the information used in the present work is scattered in studies written under different perspectives: we have historical accounts of algebraic topology as a whole [29], accounts

This work is concerned with the existence and regularity of solutions to the Neumann problem associated with a Ornstein–Uhlenbeck operator on a bounded and smooth convex set K of

In the special case when the boundary of the domain G is diffeomor- phic to a 3-dimensional sphere, the fact that the closed complex tangential curve ⊂ S ⊂ ∂ G mentioned above does

Recently Tsirelson [11] constructed an example of a reflexive Banach space with unconditional basis which contains no super-reflexive subspace and no subsymmetric

plane sets and the frontier of such a set will be denoted by the corresponding lower case Greek letter. Points and real numbers will be denoted by capital and by lower

For coun- terexamples to any type of regularity in the interior of Ω (even the L ∞ one) of minimizers of regular variational integrals in the vectorial case and solutions to
