Quantization and process
Laurent Amour, Richard Lascar, Jean Nourrigat
This article is concerned with generalizations of pseudo-differential operators in , . The definition of the new calculi depends only on bounded measure…
Partial Differential Operators and Fourier Integral Operators in the Gevrey setting and applications
Benjamin Colmey, Richard Lascar
We state and prove here semiclassical results about the construction of asymptotic solutions by the WKB method for pseudo-differential equations of real principal type. It is a Gev…
Gevrey WKB method for PDO's of real principal type
Richard Lascar, Ivan Moyano
In this article we investigate the Gevrey version of the WKB method known in the smooth and analytic categories. We use conjugation by FIO's and sketch a calculus of FIO's in our s…
Semiclassical Gevrey operators and magnetic translations
Michael Hitrik, Richard Lascar, Johannes Sjoestrand +1
We study semiclassical Gevrey pseudodifferential operators acting on the Bargmann space of entire functions with quadratic exponential weights. Using some ideas of the time frequen…
Semiclassical Gevrey operators in the complex domain
Michael Hitrik, Richard Lascar, Johannes Sjoestrand +1
We study semiclassical Gevrey pseudodifferential operators, acting on exponentially weighted spaces of entire holomorphic functions. The symbols of such operators are Gevrey functi…
Weyl calculus in Wiener spaces and in QED
Laurent Amour, Richard Lascar, Jean Nourrigat
The concern of this article is a semiclassical Weyl calculus on an infinite dimensional Hilbert space . If is a Wiener triplet associated to , the quantum state s…
