Thesis Title: $\mathcal{LA}$-Courant Algebroids and their Applications


In this thesis we develop the notion of $\mathcal{LA}$-Courant algebroids, the infinitesimal analogue of multiplicative Courant algebroids. Specific applications include the integration of $q$-Poisson $(\mathfrak{d},\mathfrak{g})$-structures, and the reduction of Courant algebroids. We also introduce the notion of pseudo-Dirac structures, (possibly non-Lagrangian) subbundles $W\subseteq {\mathbb{E}}$ of a Courant algebroid such that the Courant bracket endows $W$ naturally with the structure of a Lie algebroid. Specific examples of pseudo-Dirac structures arise in the theory of $q$-Poisson $(\mathfrak{d},\mathfrak{g})$-structures.

Everyone welcome. Coffee will be served in the math lounge before the exam.
