Closed access Metadata (CSL-JSON)
DOI 10.1063/1.5000646
Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

In this paper, we study the solvability of a singular integral equation arising in the theory of boundary value problems for the heat equation in an infinite angular domain. With the help of thermal potentials, the boundary value problem of heat conduction is reduced to a singular integral Volterra equation of the second kind. The corresponding homogeneous integral equation was investigated by us earlier in the previous paper of M.T. Jenaliyev and M.I. Ramazanov, and it was shown that in some weight class of essentially bounded functions it has, along with a trivial solution, a family of nontrivial solutions up to a constant factor. In this paper we study the nonhomogeneous integral equation, for which a representation of the general solution is found with the help of the resolvent constructed by us. Estimates of the resolvent are established.
