Data confidence 70 medium
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

On spectral question of the Cauchy-Riemann operator with homogeneous boundary value conditionsIn this paper we consider the eigenvalue problem for the Cauchy-Riemann operator with homogeneous Dirichlet type boundary conditions.The statement of the problem is justified to the theorem of M. Otelbaev and A.N. Shynybekov, which implies the correctness of the considered problem.As an example, non-local boundary conditions and Bitsadze-Samarskii type boundary conditions are given.It is taken into account that the above spectral problem for a differential Cauchy-Riemann operator with homogeneous boundary conditions of the Dirichlet type type is reduced to a singular integral, also reduces to a linear integral equation of the second kind with a continuous kernel.And it is also taken into account that the index of the singular integral equation is zero and the Noetherian condition is obtain.It is proved that the considered spectral problem does not have eigenvalues, that is, for any complex ?, has only the zero solution and thus the Cauchy-Riemann spectral problem is a Volterra problem.
