Extensions of Lie algebroids

I will explain the notion of extension for Lie algebroids, and introduce Ehresmann connections in this context. The approach includes non-abelian extensions, and Lie algebroids over different bases. Particular attention will be payed to examples. The talk will mainly rely on recent work that can be found at the following link: http://eprintweb.org/S/article/math/0810.1462
