Wave front sets with respect to Banach spaces of ultradistributions. Characterisation via the short-time Fourier transform
Pavel Dimovski, Bojan Prangoski
We define ultradistributional wave front sets with respect to translation-modulation invariant Banach spaces of ultradistributions having solid Fourier image. The main result is th…

On the characterisations of wave front sets via the short-time Fourier transform
Stevan Pilipovic, Bojan Prangoski
It is well known that the classical and Sobolev wave fronts were extended into non-equivalent global versions by the use of the short-time Fourier transform. In this very short pap…
