Non-harmonic -elliptic pseudo differential operators on manifolds
Aparajita Dasgupta, Vishvesh Kumar, Lalit Mohan +1
In this article, we introduce and study -elliptic pseudo-differential operators in the framework of non-harmonic analysis of boundary value problems on a manifold with bound…
Discrete time-dependent wave equation for the Schrödinger operator with unbounded potential
Aparajita Dasgupta, Shyam Swarup Mondal, Michael Ruzhansky +1
In this article, we investigate the semiclassical version of the wave equation for the discrete Schrödinger operator, on t…
Discrete Heat Equation with irregular thermal conductivity and tempered distributional data
Marianna Chatzakou, Aparajita Dasgupta, Michael Ruzhansky +1
In this paper, we consider a semi-classical version of the nonhomogeneous heat equation with singular time-dependent coefficients on the lattice . We establish…
Multilinear Fourier Integral operators on modulation spaces
Aparajita Dasgupta, Lalit Mohan, Shyam Swarup Mondal
In this article, we study properties of multilinear Fourier integral operators on weighted modulation spaces. In particular, using the theory of Gabor frames, we study boundedness…
