Abstract: Abstract We show that supercocycles on super L ∞ -algebras capture, at the rational level, the twisted cohomological charge structure of the fields of M -theory and of type IIA string theory. We show that… read more here.

Abstract: Abstract We consider an energy functional motivated by the celebrated K 13 {K_{13}} problem in the Oseen–Frank theory of nematic liquid crystals. It is defined for sphere-valued functions and appears as the usual Dirichlet energy… read more here.
