Transformations of Currents in Sigma-Models with Target Space Supersymmetry
Vinicius Bernardes, Andrei Mikhailov, Eggon Viana
We develop a framework for systematic study of symmetry transformations of sigma-model currents in a special situation, when symmetries have a well-defined projection onto the targ…

Derived brackets in bosonic string worldsheet sigma-model
Vinícius Bernardes, Andrei Mikhailov, Eggon Viana
We study the worldsheet theory of bosonic string from the point of view of the BV formalism. We explicitly describe the derived Poisson structure which arizes when we expand the Ma…
