$M$ -Ellipticity of Fredholm Pseudo-Differential Operators on $L^{p} (R^{n})$ and Gårding's Inequality

Aparajita Dasgupta, Lalit Mohan

In this paper, we study the $M$ -ellipticity of Fredholm pseudo-differential operators associated with weighted symbols on $L^{p} (R^{n})$ , $1 < p < \infty$ . We also prove the G…

Discrete time-dependent wave equations I. Semiclassical analysis

Aparajita Dasgupta, Michael Ruzhansky, Abhilash Tushir

In this paper we consider a semiclassical version of the wave equations with singular Hölder time-dependent propagation speeds on the lattice $ℏ Z^{n}$ . We allow the pr…

Two wavelet multipliers and Landau-Pollak-Slepian operators on locally compact abelian groups associated to right- $H$ -translation-invariant functions

Aparajita Dasgupta, Swaraj Paul, Santosh Kumar Nayak

By using a coset of closed subgroup, we define a Fourier like transform for locally compact abelian (LCA) topological groups. We studied two wavelet multipliers and Landau-Pollak-S…
