Structure exact interpolation space in the interpolation of weighted Lebesgue spaces
Efimov A. I.
UDC 517.982

For Lebesgue spaces A, B, C, D, E with additional conditions, found Lebesgue space F(E) such that the following statements are equivalent: 1) The pair E, F is said to have the interpolation property relative to A, B and C, D. 2) Space F(E) is a subspace of Banach space F.

On edge-regular graphs with b 1 =5
Kazarina V. I., Makhnev A. A.
UDC 519.14

Nonoriented v-vertex graph, in which degree of each vertex is equal k and each edge lies in λ triangles is called edge-regular graph with parameters (v,k,λ) . Set b 1 =kλ1 . At the book "Distance-Regular Graphs" it is proved that connected graph with b 1 =1 is polygon or complete multipartite graph K n×2 . Makhnev A. A. obtained the description of edge-regular graphs with b 1 3 and b 1 =4 , k10 . In this paper it is classified connected edge-regular graphs with b 1 =5 and either graph is strongly regular or k14 .

Exact solutions for thermoelasticity problems
Rodionov A. Yu.
UDC 517.958

We apply holomorphic expansions to the coupled linear system of thermoelasticity. Explicit solutions in form of functional series with the terms dependent on three complex variables are obtained. We also study the case of degeneration of the mentioned series resulted in elementary solutions.
