T-Weyl calculus
Gruia Arsu
Let be a symplectic vector space and let be a linear map that satisfies a certain condition of non-degeneracy. We define the Schur multipl…
On Kato-Sobolev type spaces
Gruia Arsu
We study an increasing family of spaces by adapting the techniques used in the study of Beurling algebras by Coifman and Meyer (1978).…
On Kato-Sobolev spaces
Gruia Arsu
We investigate some multiplication properties of Kato-Sobolev spaces by adapting the techniques used in the study of Beurling algebras by Coifman and Meyer. We develop an analytic…
On Kato-Sobolev spaces. The Wiener-Lévy theorem for Kato-Sobolev algebras
Gruia Arsu
We investigate some multiplication properties of Kato-Sobolev spaces by adapting the techniques used in the study of Beurling algebras by Coifman and Meyer. Also we develop an anal…
On Schatten-von Neumann class properties of pseudo-differential operators. Boulkhemair's method
Gruia Arsu
We investigate the Schatten-von Neumann properties of pseudo-differential operators using the method proposed by A. Boulkhemair in \cite{Boulkhemair 2}. The symbols are elements of…
On Schatten-von Neumann class properties of pseudo-differential operators. Cordes' lemma
Gruia Arsu
We prove an extended version of Cordes' lemma concerning trace-class properties of some special pseudo-differential operators. This version of Cordes' lemma is used to improve the…
