On chiral differential operators over homogeneous spaces

Vassily Gorbounov, Fyodor Malikov, Vadim Schechtman

In this note we study algebras of chiral differential operators over an algebraic group and over homogeneous spaces $G / G^{'}$ where $G$ is simple and $G^{'}$ is unipotent or parabolic.

Gerbes of chiral differential operators. III

Vassily Gorbounov, Fyodor Malikov, Vadim Schechtman

This note is a sequel to "Gerbes of chiral differential operators. II", math.AG/0003170. We study gerbes of chiral differential operators acting on the exterior algebra $Λ E$ of a v…

Gerbes of chiral differential operators. II

Vassily Gorbounov, Fyodor Malikov, Vadim Schechtman

Results of our previous note, "Gerbes of chiral differential operators" (Math. Res. Letters, 7(2000), 55-66), are discussed in the algebraic category.
