On Schrödinger Pseudo-Multipliers and their Commutators
Sayan Bagchi, Riju Basak, Joydwip Singh +1
In this article, we establish the unweighted and weighted -boundedness of pseudo-multipliers associated with a class of Schrödinger operators, this generalizes the result of o…
On some operator-valued Fourier pseudo-multipliers associated to Grushin operators
Sayan Bagchi, Riju Basak, Rahul Garg +1
This is a continuation of our work [BBGG23, BBGG22] where we have initiated the study of sparse domination and quantitative weighted estimates for Grushin pseudo-multipliers. In th…
Sparse bounds for pseudo-multipliers associated to Grushin operators, II
Sayan Bagchi, Riju Basak, Rahul Garg +1
In this article, we establish pointwise sparse domination results for Grushin pseudo-multipliers corresponding to various symbol classes, as a continuation of our investigation ini…
Sparse bounds for pseudo-multipliers associated to Grushin operators, I
Sayan Bagchi, Riju Basak, Rahul Garg +1
In this article, we prove sharp quantitative weighted -estimates for Grushin pseudo-multipliers satisfying Hörmander's condition as an application of pointwise domination of G…
Homogeneous Fourier and Weyl multipliers on Sobolev spaces related to the Heisenberg group
Riju Basak, Rahul Garg, Sundaram Thangavelu
Inspired by the work of A. Bonami and S. Poornima that a non-constant function which is homogeneous of degree cannot be a Fourier multiplier on homogeneous Sobolev spaces, we e…
