Idéaux fermés d'algèbres de Beurling analytiques sur le bidisque

We study the closed ideal in the Beurling algebras of holomorphic function f in the bidisc such that

     

Some functional inverse Santaló inequalities

Let be a log-concave function and for z∈Rn, define

     

Duality techniques for certain integral transforms to be starlike

For β<1, let denote the class of all normalized analytic functions f such that

     

Semiclassical stationary states of Nonlinear Schrödinger equations with an external magnetic field

In this paper we obtain multiple solutions of the nonlinear Schrödinger equation with an external magnetic field
