Conformally covariant pseudo-differential operators

Differential Geometry and its Applications, 2000
Conformal Geometry has found applications in the study of general relativity, in the study of the famous Yamabe problem, as well as in other areas. The study of conformally covariant operators was traditionally focused on differential operators.

Weak-type (1,1) bounds for a class of operators with discrete kernel

Revista Integración, 2015
In this paper we investigate the weak continuity of a certain class of operators with kernel defined on Z×Z. We prove some results on the weak boundedness of discrete analogues of Calderón-Zygmund operators.

Dimension independent data sets approximation and applications to classification

Advanced Modeling and Simulation in Engineering Sciences
We revisit the classical kernel method of approximation/interpolation theory in a very specific context from the particular point of view of partial differential equations.

A variant of the formal theorem on the zeros of linear differential operators

Известия высших учебных заведений. Поволжский регион: Физико-математические науки
Background. In the theory of linear differential equations, transformations generated by differential substitutions of dependent variables play an essential role. The study of these transformations led by A.I.
