Pure Spinors for General Backgrounds
Pietro Fre', Pietro Antonio Grassi
We show the equivalence of the different types of pure spinor constraints geometrically derived from the Free Differential Algebras of N=2 d=10 supergravities. Firstly, we compute…

Y-Formalism and Curved Beta-Gamma Systems
Pietro Antonio Grassi, Ichiro Oda, Mario Tonin
We adopt the Y-formalism to study beta-gamma systems on hypersurfaces. We compute the operator product expansions of gauge-invariant currents and we discuss some applications of th…

Free Differential Algebras, Rheonomy, and Pure Spinors
Pietro Fré, Pietro Antonio Grassi
We report on progresses on the derivation of pure spinor constraints, BRST algebra and BRST invariant sigma models a la pure spinors from the algebraic structure of the FDA underly…
