Talk	Oral abstract	Title	Numerical Treatment of Uehling-Ulenbeck Equations in Relativistic Plasma: Fast scheme with GPGPU Usage
Coauthors	Prakapenia, Mikalai; Vereshchagin, Gregory
Abstract	We propose a fast numerical scheme for Uehling-Ulenbeck equations, i.e. Boltzmann equations with inclusion of quantum degeneracy. The presented case treats isotropic mildly relativistic electron-positron-photon plasma including all two- and three-particle interactions (bremsstrahlung, double Compton scattering, etc.). The scheme, however, is much more general and can be applied to the wide class of systems with kinetic description. We propose a fast deterministic algorithm for multidimensional integration of collision integrals in such systems, that includes suitable angular reparametrization.

Talk	Oral abstract	Title	Photospheric emission in the brightest GRBs
Coauthors	Vereshchagin, Gregory
Abstract	Based on available observational data we compute the parameters of the photosphere for most bright GRBs with well established thermal components in their prompt phase. We compare our results with estimates in the literature.
