Aissa Wade's (Penn State) talk. Title: Dirac structures, contact geometry. Abstract: The theory of Dirac structures on manifolds, initiated by T. Courant and A. Weinstein in the mid-eighties, was originally aimed at providing a geometric framework for the study of constrained mechanical systems. Dirac manifolds include both pre-symplectic and Poisson manifolds. In 2002, N. Hitchin introduced the notion of a generalized complex structure, incorporating complex structures into the theory of Dirac structures. In this talk, we will describe generalized complex structures and give some examples. We will also present new connections between the theory of Dirac structures and contact geometry.
