On asymptotics of the spectrum of an integral operator with a logarithmic kernel of a special form. (English. Russian original) Zbl 1535.45009
Differ. Equ. 59, No. 12, 1721-1733 (2023); translation from Differ. Uravn. 59, No. 12, 1680-1691 (2023).
The author analyses a convolution-type equation on a finite interval having a kernel characterised by a logarithmic function whose argument depends on a hyperbolic cosine. The asymptotic behaviour of the spectrum of the integral operator associated with this equation is deduced by considering a corresponding conjugation problem for analytic functions and a resulting infinite system of linear algebraic equations.
