Dirac brushes (or, the fractional Fourier transform of Dirac combs)
Joe Viola
In analogy with the Poisson summation formula, we identify when the fractional Fourier transform, applied to a Dirac comb in dimension one, gives a discretely supported measure. We…

Quaternionic structure and analysis of some Kramers-Fokker-Planck operators
Mona Ben Said, Francis Nier, Joe Viola
The present article is concerned with global subelliptic estimates for Kramers-Fokker-Planck operators with polynomials of degree less than or equal to two. The constants appearing…
