DOI: 10.1093/mnras/stab2227
Abstract: The excursions of star clusters and galaxies around statistical equilibria are studied. For a stable ergodic model Antonov’s Hermitian operator on six-dimensional phase space has the normal modes as its eigenfunctions. The excitation energy of… read more here.

Abstract: A simple model of charge transport is provided by a classical particle in a random potential and a dissipative coupling to the environment. The corresponding nonequilibrium steady state (NESS) can be determined analytically when both… read more here.

DOI: 10.1134/s1063780x17010056
Abstract: The theory of van Kampen waves in plasma with an arbitrary anisotropic distribution function is developed. The obtained solutions are explicitly expressed in terms of the permittivity tensor. There are three types of perturbations, one… read more here.

DOI: 10.15672/hujms.1343052
Abstract: The focus of this paper revolves around investigating the harmonicity aspects of various mappings. Firstly, we explore the harmonicity of the canonical projection π : TM → M, where M denotes a Riemannian manifold and… read more here.
