Nonabelian 2-forms and loop space connections from SCFT deformations
Urs Schreiber
It is shown how the deformation of the superconformal generators on the string's worldsheet by a nonabelian super-Wilson line gives rise to a covariant exterior derivative on loop…

Pohlmeyer invariants are expressible in terms of DDF invariants
Urs Schreiber
It is shown that the Pohlmeyer invariants of the classical bosonic string are a proper subset of the classical DDF invariants. This makes the quantization of the Pohlmeyer invarian…

Covariant Hamiltonian evolution in supersymmetric quantum systems
Urs Schreiber
We develop a general formalism for covariant Hamiltonian evolution of supersymmetric (field) theories by making use of the fact that these can be represented on the exterior bundle…
