On canonical embeddings of complex projective spaces in real projective spaces
Journal of Mathematical Sciences - Tập 142 - Trang 2367-2376 - 2007
In this paper, we construct a natural embedding
$$\sigma :\mathbb{C}P_\mathbb{R}^{n} \to \mathbb{R}P^{n^2 + 2n} $$
of the complex projective space ℂP
n considered as a 2n-dimensional, real-analytic manifold in the real projective space

Boundary-Value Problem for Nonuniformly Elliptic Equations with Power Singularities
Journal of Mathematical Sciences - Tập 278 - Trang 748-760 - 2024
By using a priori estimates and the Riesz theorem, we investigate a boundary-value problem for nonuniformly 2b -elliptic equations with arbitrary power singularities in the coefficients of the equation and boundary conditions on a certain set of points. We establish the existence and obtain an integral representation of the unique solution of the formulated boundary-value problem in Hölder spaces ...... hiện toàn bộ
INTEGRAL OPERATORS, GUIDING POTENTIALS AND PERIODIC SOLUTIONS OF DIFFERENTIAL INCLUSIONS ON NON-COMPACT LIE GROUPS
Journal of Mathematical Sciences - Tập 266 - Trang 667-674 - 2022
We obtain the existence of a periodic solution for differential inclusions with lower semi-continuous right-hand sides on non-compact Lie groups. The construction is based on the combination of the method of guiding functions and the technique of integral operators with parallel translation.
Well-Posedness of Boundary-Value Problems for Conditionally Well-Posed Integro-Differential Equations and Polynomial Approximations of Their Solutions
Journal of Mathematical Sciences - Tập 272 - Trang 816-825 - 2023
The this paper, we introduce a pair of Sobolev spaces with special Jacobi–Gegenbauer weights, in which the general boundary-value problem for a class of ordinary integro-differential equations characterized by the positivity of the difference of orders of the inner and outer differential operators is well-posed in the Hadamard sense. Based on this result, we justify the general polynomial projecti...... hiện toàn bộ
Feasibility of parallel computations on a three-dimensional associative parallel processor
Journal of Mathematical Sciences - Tập 23 - Trang 1979-1996 - 1983
A three-dimensional associative parallel processor (APP3) is introduced and a program without loops and jumps is developed which for every algorithmically computable function 1) computes the function given a finite but sufficiently large memory, dependent on the function and the argument, 2) recognizes the domain of its definition on infinite memory.

Action-type axiomatizable classes of group representations
Journal of Mathematical Sciences - Tập 142 - Trang 1915-1922 - 2007
The paper adjoins the work of B. I. Plotkin and S. M. Vovsi, Varieties of Representations of Groups (Zinatne, Riga (1983)), and turns out to be, in a sense, its continuation. In the former, the varieties of representations have been considered. As a matter of fact, the varieties under consideration are action-type varieties. This paper studies other classes of representations, axiomatizable in a s...... hiện toàn bộ
