In the same way as the known spacesM p ,M p , andI p are constructed on the basis of the spaceL p (−1, 1), we construct the corresponding “limit” spacesM E ,M E , andI E on the real line on the basis of a symmetric function ...

Two definitions of wild *-algebras are considered from the point of view of the theory of representations. We present methods for proving the fact that a *-algebra is wild. It is also shown that if a algebra isp-wild, then ...

We obtain sufficient conditions that should be imposed on a functionf in order that, for ergodic Markov chains, the sum 1n‾√∑k=0n−1f(Xk) be asymptotically normal.

Essential self-adjointness of Dirichlet operators of Gibbs measures on infinite products of manifolds

The notion of a convex set is generalized. In the definition of ordinary convexity, sums of products of vectors and numbers are used. In the generalization considered in this paper, the role of numbers is played by matrices; ...

We obtain duality relations for local periodic cubic and parabolic splines of minimal defect and establish some of their corollaries.

It is proved that the wreath product of a second-order group and the commutant of a dihedral group is imbedded into a multiplicative group of a modular group algebra of a dihedral group of order 2 n . This implies that the ...

For functionsf which have an absolute continuous (n−1)th derivative on the interval [0, 1], it is proved that, in the case ofn>4, the inequality ‖‖f(n−2)‖‖∞⩽4n−2(n−1)!‖f‖∞+‖‖f(n)‖‖∞/2 holds with the exact constant 4 n−2(n−1)!.

The exact dependence of constants in Jackson-type inequalities on the rate of convergence of the Diophantine approximations of certain numbers is obtained.

We show that, in a Banach space, continuous random processes constructed by using solutions of the difference equationX n =A n X n+1+V n , n=1, 2,..., converge in distribution to a solution of the corresponding operator equation.
