The Wigner distribution of Gaussian tempered generalized stochastic processes
Patrik Wahlberg
We define the Wigner distribution of a tempered generalized stochastic process that is complex-valued symmetric Gaussian. This gives a time-frequency generalized stochastic process…

Polynomially oscillatory multipliers on Gelfand-Shilov spaces
Alexandre Arias Junior, Patrik Wahlberg
We study continuity of the multiplier operator acting on Gelfand--Shilov spaces, where is a polynomial on of degree at least two with real coefficients.…
