Integration of geodesic flows on homogeneous spaces: the case of a wild lie group
A. A. Magazev, I. V. Shirokov
We obtain necessary and sufficient conditions for the integrability in quadratures of geodesic flows on homogeneous spaces with invariant and central metrics. The proposed inte…

Darboux Coordinates on K-Orbits and the Spectra of Casimir Operators on Lie Groups
I. V. Shirokov
We propose an algorithm for obtaining the spectra of Casimir (Laplace) operators on Lie groups. We prove that the existence of the normal polarization associated with a linear func…

Bifurcations and a chaos strip in states of long Josephson junctions
K. N. Yugay, N. V. Blinov, I. V. Shirokov
Stationary and nonstationary, in particular, chaotic states in long Josephson junctions are investigated. Bifurcation lines on the parametric bias current-external magnetic field p…
