We study the dissipative evolution of (0+1)-dimensionally expanding media with Bjorken symmetry using Boltzmann equation for massive particles in relaxation-time approximation. Breaking conformal by a mass induces non-zero bulk viscous pressure medium. It is shown that even small (in units local temperature) drastically modifies well-known attractor shear Reynolds number previously observed mas...

We introduce the notion of a conformal de Rham complex of a Riemannian manifold. This is a graded differential Banach algebra and it is invariant under quasiconformal maps, in particular the associated cohomology is a new quasiconformal invariant.

We discuss non-relativistic conformal algebras generalizing the Schrödinger algebra. One instance of these algebras is a conformal, acceleration-extended, Galilei algebra, which arises also as a contraction of the relativistic conformal algebra. In two dimensions, this admits an “exotic” central extension, whereby boosts do not commute. We study general properties of non-relativistic conformal ...

We show that the fusion rule for a modular invariant Ertype conformal field theory, which is constructed from the one for the A,(l) Kac-Moody algebra by naive extension, is not associative. Then by imposing .further restrictions to this naive fusion rule, we obtain associative fusion rules for the E7-type conformal field theory. Unlike the case of an E6-type conformal field theory, these fusion...
