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 Spectral multiplier theorem for sub-Laplacians with drift on Métivier groups

Nishta Garg, Joydwip Singh

In this paper, we prove a spectral multiplier theorem for sub-Laplacians with drift on Métivier groups. We improve the result of [Martini, Ottazzi and Vallarino, Rev. Mat. Iberoam,…

Stein's square function associated with the Bochner-Riesz means on Métivier groups and its applications

Joydwip Singh

In this paper, we study the $L^{p}$ -boundedness of Stein's square function $S^{α} (L)$ associated with the sub-Laplacian $L$ on Métivier group $G$ . A key…
