Conformal Field Theories on the Two-Torus and Quotients of SL2(Z)
Antoine Coste, Giovanni Felder
We present remarkable properties of the groups SL2(Z/NZ) which might be useful in detailed studies of some quotients appearing in Conformal Field Theories.
Formal Lagrangian Operad
Alberto S. Cattaneo, Benoit Dherin, Giovanni Felder
Given a symplectic manifold , we may define an operad structure on the the spaces $\op^k$ of the Lagrangian submanifolds of via symplectic reduction. If $M…
Poincare-Birkhoff-Witt expansions of the canonical elliptic differential form
G. Felder, R. Rimanyi, A. Varchenko
We study the canonical U(\n)-valued elliptic differential form, whose projections to different Kac-Moody algebras are key ingredients of the hypergeometric integral solutions of el…
Relative formality theorem and quantisation of coisotropic submanifolds
Alberto S. Cattaneo, Giovanni Felder
We prove a relative version of Kontsevich's formality theorem. This theorem involves a manifold M and a submanifold C and reduces to Kontsevich's theorem if C=M. It states that the…
