On Besov and Triebel-Lizorkin spaces associated with the Grushin operator

Sayan Bagchi, Nishta Garg, Rahul Garg

In this article, we define classical and non-classical Besov and Triebel--Lizorkin spaces associated with the Grushin operator with or without drift. We establish various character…

Bilinear Bochner-Riesz Means on the Complex Sphere

Sayan Bagchi, Md Nurul Molla, Joydwip Singh +1

In this paper, we establish the boundedness of the bilinear Bochner-Riesz means $B_{R}^{α}$ on the complex sphere $S$ . More precisely, we prove that $\mathcal{B}^α_R…

On Schrödinger Pseudo-Multipliers and their Commutators

Sayan Bagchi, Riju Basak, Joydwip Singh +1

In this article, we establish the unweighted and weighted $L^{p}$ -boundedness of pseudo-multipliers associated with a class of Schrödinger operators, this generalizes the result of o…

Bilinear Bochner-Riesz Means for Grushin Operators

Sayan Bagchi, Md Nurul Molla, Joydwip Singh

This paper is devoted to the study of $L^{p_{1}} \times L^{p_{2}}$ to $L^{p}$ boundedness of the bilinear Bochner-Riesz mean $B^{α}$ associated with the Grushin operator $\math…

Bilinear Bochner-Riesz Means on Métivier groups

Sayan Bagchi, Md Nurul Molla, Joydwip Singh

In this paper, we study the $L^{p_{1}} (G) \times L^{p_{2}} (G)$ to $L^{p} (G)$ boundedness of the bilinear Bochner-Riesz means associated with the sub-Laplacian on Métivier group $G$ und…
