Large classes of nonnegative Schrodinger operators on R2 and R3 with the following properties are described: 1. The restriction of each of these opera......

There are many papers on the classification of singularities that are invariant or equivariant under the action of a finite group. However, since the ......

We give an integration by parts approach to Davies' Hardy inequality. An improvement with a strictly larger Hardy weight is thereby obtained.

The notion of the limit spectral measure of a metric triple (i.e., a metric measure space) is defined. If the metric is square integrable, then the li......

We give an estimate of the rate of convergence to zero of the norms of remotest projections on three subspaces of a Hilbert space with zero intersecti......

New results on the strong solvability in Sobolev spaces of the quasilinear Venttsel' problem for parabolic equations with discontinuous leading coeffi......

Abelian- and Tauberian-type results characterizing the quasiasymptotic behavior of distributions in S-0 '(R) in terms of their Stockwell transforms ar......

We extend homogeneous and inhomogeneous Nash-type inequalities to abstract metric-measure spaces.

In this paper, we generalize the notions of quermassintegrals, harmonic quermassintegrals, and affine quermassintegrals to p-quermassintegrals so that......

Three-dimensional manifolds carrying the structure of n-valued coset topological groups originating from the Lie groups Sp(1) and SO(3) are classified......

It is proved that the image of a stable germ of type E-6(+/-) of a Lagrangian map to R-n is homeomorphic to the germ at zero of a closed half-space.

As is known, for isolated hypersurface singularities and complete intersections of positive dimension, the Milnor number is the least upper bound for ......

The work is devoted to solving a problem of L. N. Shevrin and M. V. Sapir (Question 3.81b of the Sverdlovsk Notebook), namely, to constructing a finit......

We derive various lower bounds for the numerical radius w(A) of a bounded linear operator A defined on a complex Hilbert space, which improve the exis......

We define certain subvarieties, called theta-Hecke correspondences, in Cartesian products of diagram automorphism fixed quiver varieties. These give u......
