(2012-06-26)For general Carnot groups, we obtain coercive estimates for homogeneous di erential operators with constant coe cients, kernels of which have nite dimension. We develop new Sobolev-type integral representations of di ...

(2012-06-26)We establish estimates sharp in order for the Kolmogorov and linear widths of the classes Bsm p q ( Tk) and Lsm p q (Tk) of Nikol'skii-Besov, Lizorkin-Triebel types respectively, in the space Lr(Tk) for a certain range ...

(2012-06-26)The notion of a hypodecreasing function is introduced. Some properties of hypodecreasing functions are proved and several examples are given. It is established that the Hardy-type inequality for Lp-spaces with 0 < p < 1 ...

(2012-06-26)An inverse coe cient problem for the nonlinear biharmonic equation Au := (g(»2(u))(ux1x1 + (1/2)ux2x2)x1x1 + (g(»2(u))ux1x2)x1x2 + (g(»2(u))(ux2x2 + (1/2)ux1x1))x2x2 = F(x), in ½ R2, is considered. This problem arises ...

(2012-06-26)The convergence of families of linear polynomial operators with kernels generated by matrices of multipliers is studied in the scale of the Lp-spaces with 0 < p · +1. An element an, k of generating matrix is represented ...
-
(2012-06-26)In the paper we answer the question when in nite dimensions nite unions and intersections of closed half-spaces are shifts of sets stable under shrinkings or dilatations and give explicit descriptions of the kernels ...
-
(2012-06-26)An iterative scheme containing two asymptotically nonexpansive mappings has been used in this paper to approximate common xed points in a strictly convex Banach space. This improves and extends some known recent results ...

(2012-06-26)Let q(x) be real-valued compactly supported su ciently smooth function. It is proved that the scattering data A(−¯, ¯, k) 8¯ 2 S2, 8k > 0, determine q uniquely.
