Dissertation

Unlike a finite dimensional Lie algebra, a Lie algebroid does not always come from a Lie groupoid. Non-integrability already shows up in the case of infinite dimensional Lie algebras. I found that a Lie algebroid can nevertheless always be integrated into an étale stack with a groupoid structure, which I call a Weinstein groupoid. The converse is true too; hence the Lie algebroid version of the 1-1 correspondence between Lie algebras and Lie groups is fully established. Applying the above to Jacobi manifolds, I prove that the integrating objects of Jacobi manifolds are contact groupoids. I also have determined the integrability conditions.
