Pointwise convergence to initial data of heat and Hermite-heat equations in Modulation Spaces

Divyang G. Bhimani, Rupak K. Dalai

We characterize weighted modulation spaces (data space) for which the heat semigroup converges pointwise to the initial data as time tends to zero. Here stan…

A unified framework for pointwise convergence to the initial data of heat equations in metric measure spaces

Divyang G. Bhimani, Anup Biswas, Rupak K. Dalai

Given a metric measure space satisfying the volume doubling condition, we consider a semigroup and the associated heat operator. We propose general…

Quaternion Weyl Transform and some uniqueness results

Rupak Kumar Dalai, Somnath Ghosh, R. K. Srivastava

In this article, we study the boundedness and several properties of the quaternion Wigner transform. Using the quaternion Wigner transform as a tool, we define the quaternion Weyl…

Injectivity of spherical mean on Métivier Group

Rupak Kumar Dalai, R. K. Srivastava

In this article, we study the injectivity of the spherical mean for continuous functions on the Métivier group. The spherical mean is injective for $f(z, .)\in L^p(\mathbb{R}^m),~1…

Spherical means on Métivier groups and support theorem

Rupak Kumar Dalai, Somnath Ghosh, R. K. Srivastava

Let be the space of continuous functions on the annulus in whose -twisted spherical mean, in the set up of the Métivier group, vanishes over…
