Partial inverse problems for quadratic differential pencils on a graph with a loop
Natalia P. Bondarenko, Chung-Tsun Shieh
In this paper, partial inverse problems for the quadratic pencil of Sturm-Liouville operators on a graph with a loop were studied. These problems consist in recovering the pencil c…

An inverse problem for the integro-differential Dirac system with partial information given on the convolution kernel
Natalia P. Bondarenko
An integro-differential Dirac system with an integral term in the form of convolution is considered. We suppose that the convolution kernel is known a priori on a part of the inter…

On recovering Sturm-Liouville differential operators with deviating argument
Natalia Bondarenko, Vjacheslav Yurko
We consider second-order functional differential operators with a constant delay. Properties of their spectral characteristics are obtained and a nonlinear inverse problem is studi…
