Linear boundary-value problems described by Drazin invertible operators

Theorem 2 is in fact a consequence of a more general result concerning the singular values of non necessarily selfadjoint compact Hankel operators.. Recall that the singular values of

Our first main result is the association of a contact vector field to an arbitrary second order linear differential operator in a contact-invariant manner.. Although we do not carry

This section is divided in two paragraphs. In the first one, we prove that the boundary value problem with zero initial data is well posed. This is merely a consequence of

• simple attacks on unbalanced cells and the biggest cell attack, • balance: balanced cells, DB: a defensive balanced player, • BUCT: a UCT player using balanced VD,.. • aBUCT: a

(It is easy to see that every solution on K can be extended to C as a solution.) Let S 1 denote the set of additive solutions defined on K. This implies that if S is

To this end, we give an explicit representation formula, using analytic semigroups, sectorial operators with Bounded Imaginary Powers, the theory of strongly continuous cosine

In order to characterize positive good measures, we introduce a framework of nonlinear analysis which have been used by Dynkin and Kuznetsov (see [16] and references therein) and
