The aim of this paper is to discuss indefinite almost Hermitian manifold
with the vanishing Bochner curvature tensor. Relations between the anti-holomorphic
sectional curvature, the holomorphic sectional curvature and ...
The two-sided estimates are obtained for two types of generalized Hardy
operators on cones of functions in weighted Lebesgue spaces with some properties of
monotonicity.
A mathematical model of the heat exchange process, where the temperature
inside some domain is controlled by m convectors acting on the boundary, is
considered. The control parameter is a vector-function, whose components ...
The DSM (dynamical systems method) version of the Newton’s method
is for solving operator equation F(u) = f in Banach spaces is discussed. If F is a
global homeomorphism of a Banach space X onto X, that is continuously ...
We obtain sufficient conditions for continuity of the eigenvalues of semibounded
quasi-differential operators of order 2n on the half-axis with respect to the
parameters that appear in the corresponding differential ...

In this paper we define the Nikol’skii-Besov and Lizorkin-Triebel spaces
(B-Nikol’skii-Besov and B-Lizorkin-Triebel spaces) in the context of the Fourier-Bessel
harmonic analysis. We establish some basic properties of ...
Applying the two-operator approach, the mixed (Dirichlet-Neumann)
boundary value problem for a second-order scalar elliptic differential equation with
variable coefficients is reduced to several systems of Boundary Domain ...
Given a closed bounded convex plane set covered by a family of open sets,
we show that there is a finite dissection of the convex set into convex subsets, each of
which lies within some open set of the covering.
