In this paper we characterize global regularity in the sense of Shubin of twisted partial differential operators of second order in dimension 2. These operators form a class containing the twisted Laplacian, and in bi-unique correspondence with secon

Complex powers of a class of hypoelliptic pseudodifferential operators in R n , as well as their heat kernels are studied. An application to the Schatten–von Neumann property of pseudodifferential operators is given.

We prove that the Calabi–Yau equation on the Kodaira–Thurston manifold has a unique solution for every $S^1$-invariant initial datum.

In this work we consider a general class of hypoelliptic operators, for which we give an estimate of the remainder of the so-called Weyl asymptotic formula for the eigenvalues.

In this work we consider a general class of Schrodinger type operators, associated with multi-quasi-elliptic symbols. We give a precise estimate of the remainder of the so-called Weyl asymptotic formula for the eigenvalues of these operators. In orde

We describe the essential spectrum of a hypoelliptic pseudo-differential operator which is the sum of a constantcoefficients operator and an operator with coefficients vanishing at infinity. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

We study the exponential decay of solutions to differential equations of hypoelliptic type (see Definition 2.1). In particular we find sufficient conditions on the differential operator A in order for estimates of the kind $$ e^{\varepsilon \left\lan
