The Kato conjecture for some classes of nonlocal operators
 

Abstract: The Kato conjecture for some classes of nonlocal operators In 1961, T. Kato has formulated the following problem: “Is it true that the domain of square root from regular accretive operator is equal to the domain of square root from adjoint operator?”

Sufficient conditions for fulfilment of the Kato conjecture were studied by T. Kato, J. Lions and others. J. Lions has proved that strongly elliptic differential operators of 2m order with smooth coefficients and homogeneous Dirichlet conditions on a smooth boundary satisfy the Kato conjecture. For strongly elliptic differential operators of 2m order with measurable bounded coefficients corresponding result was obtained by P. Auscher, S. Hofman, A. McIntosh, and P. Tchamitchian.

In this lecture we consider two types of nonlocal elliptic operators: strongly elliptic functional differential operators and elliptic differential-difference operators with degeneration. We prove that these operators satisfy the Kato square root conjecture, see [1, 2]. The publication has been prepared with the support of the “RUDN University Program 5-100” and the Russian Foundation for Basic Research (project No. 17-01-00401).

Functional properties of Sobolev extensions
 

Abstract: Functional properties of Sobolev extensions A given domain Ω in a Euclidean space may or may not have the property that each function in a Sobolev space over this domain can be extended to a function in the analogous Sobolev space over the entire Euclidean space.

I will review functional properties of this condition, e.g. invariance under a change of variable. Some of the results are from a manuscript that is about to be finished.
