Bisingular pseudodifferential operators on products of compact Lie groups

G. Drei, S. Federico, A. Parmeggiani

In this paper we develop the calculus of bisingular pseudodifferential operators on the product compact Lie groups, which extends the one that was earlier introduced by the…

Weyl Calculus on Graded Groups

Serena Federico, David Rottensteiner, Michael Ruzhansky

The aim of this paper is to establish a pseudo-differential Weyl calculus on graded nilpotent Lie groups which extends the celebrated Weyl calculus on . To reach…

Poincaré inequalities on Carnot Groups and spectral gap of Schrödinger operators

Marianna Chatzakou, Serena Federico, Boguslaw Zegarlinski

In this work we give a sufficient condition under which the global Poincaré inequality on Carnot groups holds true for a large family of probability measures absolutely continuous…

On the uniqueness of variable coefficient Schrödinger equations

Serena Federico, Zongyuan Li, Xueying Yu

We prove unique continuation properties for linear variable coefficient Schrödinger equations with bounded real potentials. Under certain smallness conditions on the leading coeffi…

Subelliptic sharp Gårding inequality on compact Lie groups

Duván Cardona, Serena Federico, Michael Ruzhansky

In this work we establish a subelliptic sharp Gårding inequality on compact Lie groups for pseudo-differential operators with symbols belonging to global subelliptic Hörmander clas…

On a class of pseudodifferential operators on the product of compact Lie groups

Serena Federico, Alberto Parmeggiani

In this paper a bisingular pseudodifferential calculus, along the lines of the one introduced by L. Rodino in [12], is developed in the global setting of a product of compact Lie g…

Sharp Strichartz estimates for some variable coefficient Schrödinger operators on

Serena Federico, Gigliola Staffilani

In the first part of the paper we continue the study of solutions to Schrödinger equations with a time singularity in the dispersive relation and in the periodic setting. In the se…

-Poincaré inequalities on Carnot Groups with filiform type Lie algebra

Marianna Chatzakou, Serena Federico, Boguslaw Zegarlinski

In this paper, we prove (global) -Poincaré inequalities for probability measures on nilpotent Lie groups with filiform Lie algebra of any length. The probability measures under…

Smoothing and Strichartz estimates for degenerate Schrödinger-type equations

Serena Federico, Michael Ruzhansky

In this paper we focus on the validity of some fundamental estimates for time-degenerate Schrödinger-type operators. On one hand we derive global homogeneous smoothing estimates fo…

Smoothing effect for time-degenerate Schrödinger operators

Serena Federico, Gigliola Staffilani

In this work we consider an example of a linear time-degenerate Schrödinger operator. We show that with the appropriate assumptions the operator satisfies a Kato smoothing effect.…

On the Local solvability of a class of degenerate second order operators with complex coefficients

Serena Federico, Alberto Parmeggiani

We study the local solvability of a class of operators with multiple characteristics. The class considered here complements and extends the one studied in [9], in that in this pape…

Sufficient conditions for local solvability of some degenerate PDO with complex subprincipal symbol

Serena Federico

We will show a local solvability result for a class of degenerate second order linear partial differential operators with a complex subprincipal symbol. Due to the form of the oper…
