Published in 2018 at "Analysis Mathematica"

DOI: 10.1007/s10476-018-0609-y

Abstract: In this paper, we prove the boundedness and compactness of localization operators associated with Riemann–Liouville wavelet transforms, which depend on a symbol and two Riemann–Liouville wavelets on Lp(dνα), 1 ≤ p ≤ ∞. read more here.

Published in 2021 at "Analysis Mathematica"

DOI: 10.1007/s10476-021-0091-9

Abstract: We introduce and study the k-Hankel Gabor transform. We investigate the localization operators for this transform. In particular, we study their trace class properties and we prove that they belong to the Schatten-von Neumann class.… read more here.

Published in 2017 at "Journal of Pseudo-Differential Operators and Applications"

DOI: 10.1007/s11868-017-0196-x

Abstract: In this paper the notion of a Dunkl two-wavelet is introduced. The resolution of the identity formula for the Dunkl continuous wavelet transform is then formulated and proved. Calderón’s type reproducing formula in the context… read more here.
