Inverse spectral problem for the differential equation of the second order with singularity
(VSP BV-C/O BRILL ACAD PUBL, 1998)
In this article, for given values of {lambda(n)} and {mu(n)} constructing a differential operator, which has a singularity, has exploined. In order to acomplish this, lambda(n) and mu(n) have to have some certain asymptotic. ...
Trace formula for the Sturm-Liouville operator with singularity
(VSP BV-C/O BRILL ACAD PUBL, 1998)
Let mu(1), mu(2),..., mu(n),... be the Dirichlet spectrum of the operator -d(2)/dx(2) + q(x) acting on L-2(0,pi). In the special case where q(x) = 0, mu(n) = n(2). In the [1] and others discovered the asymptotic formula ...
