On extension of Calderón-Zygmund type singular integrals and their commutators
Sayan Bagchi, Rahul Garg, Joydwip Singh
Motivated by the recent works [Huan Yu, Quansen Jiu, and Dongsheng Li, 2021] and [Yanping Chen and Zihua Guo, 2021], we study the following extension of Calderón-Zygmund type singu…
An analogue of Ingham's theorem on the Heisenberg group
Sayan Bagchi, Pritam Ganguly, Jayanta Sarkar +1
We prove an exact analogue of Ingham's uncertainty principle for the group Fourier transform on the Heisenberg group. This is accomplished by explicitly constructing compactly supp…
On the maximal function associated to the spherical means on the Heisenberg group
S. Bagchi, S. Hait, L. Roncal +1
In this paper we deal with lacunary and full versions of the spherical maximal function on the Heisenberg group , for . By suitable adaptation of an approach…
Fourier Multipliers on the Heisenberg groups revisited
Sayan Bagchi
In this paper, we give explicit expressions of differential-difference operators appeared in the hypothesis of the general Fourier multiplier theorem associated to the Heisenberg g…
Heisenberg uniqueness pairs corresponding to finite number of parallel lines
Sayan Bagchi
In this paper we study the Heisenberg uniqueness pairs corresponding to finite number of parallel lines . We give a necessary condition and a sufficient condition for a subset $…
