An anisotropic integral operator in high temperature superconductivity
Boris Mityagin
A simplified model in superconductivity theory studied by P. Krotkov and A. Chubukov \cite{KC1,KC2} led to an integral operator -- see (1), (2). They guessed that the equation…

Trace formula and spectral Riemann surfaces for a class of tri-diagonal matrices
Plamen Djakov, Boris Mityagin
For tri-diagonal matrices arising in the simplified Jaynes--Cummings model, we give an asymptotics of the eigenvalues, prove a trace formula and show that the Spectral Riemann Surf…
