Extension of Localisation Operators to Ultradistributional Symbols With Super-Exponential Growth

Stevan Pilipović, Bojan Prangoski, Đorđe Vučković

In the Gelfand-Shilov setting, the localisation operator $A_a^{{\phi }_1,{\phi }_2}$ is equal to the Weyl operator whose symbol is the convolution of $a$ with the Wigner transform of the windo…
