Deformation Theory of Courant Algebroids via the Rothstein Algebra
Frank Keller, Stefan Waldmann
In this paper we define Courant algebroids in a purely algebraic way and study their deformation theory by using two different but equivalent graded Poisson algebras of degree -2.…

Formal Deformations of Dirac Structures
Frank Keller, Stefan Waldmann
In this paper we set-up a general framework for a formal deformation theory of Dirac structures. We give a parameterization of formal deformations in terms of two-forms obeying a c…
