The papers I have selected include the three Il'eat memoirs in the first volumes of Acta Math. These are the papers which made his reputation and they include many results and proofs which are now standard. They are preceded by an , unedited memoir written by Poincare in May at the height of his , creative ferment.

ipdwew0030atl2.public.registeredsite.com/sitemap125.xml This paper is aimed at giving a general construction of algebras of generalized Gevrey ultradistributions and the microlocal analysis suitable for them. It also makes explicit the contribution of the mollification in the embedding of ultradistributions into algebras of generalized functions. The physical and mathematical motivations for doing so are discussed and a number of examples are given.

Time-frequency analysis provides an effective description of the nonstationary random processes arising from random phenomena. These phenomena have typically a time-varying spectral content, which can be represented by using time-frequency distributions.

The stochastic differential equation that models the nonstationary random process can be transformed in the time-frequency domain, and the properties of the resulting deterministic timefrequency equation clarify the nature of the nonstationary random process. We review the transformation to the time-frequency domain, and we prove the correctness of the obtained time-frequency equation. In this paper we define a variation of theWigner form depending on a linear transformation of the time-frequency plane and study the corresponding properties.

In particular we prove that the representations in this new class which satisfy the support properties are just the so-called t-Wigner forms. In this paper we present a new technique to prove optimal boundedness results for localization operators acting on Wiener amalgam spaces and, in particular, on L p spaces, first obtained in [7] by another method. This new proof does not require the Schur-type Test introduced and employed there. We also briefly discuss the optimality of these results.
