Abstract: In this series of lectures, we'd like to explore higher symplectic stacks in differential geometry with the framework of Lie n-groupoids. We'll talk, in more or less details on,

1. Kan simplicial objects with Grothendieck pretopologies, Lie n-groupoids;

2. Lie 2-groups as categorification of Lie groups, Morita equivalence: via a) hypercovers, b) weak equivalences, c) bibundles (sometimes called Hilsum-Skandalis bibundles);

3.NQ manifolds (a sort of d.g. manifolds), Lie n-algebroids (as tangent complex of Lie n-groupoids);

4. m-shifted symplectic Lie n-groupoids, with example of BG (or Lie group) together with several interesting models of symplectic forms, symplectic Morita equivalence, I.M. (infinitesimal multiplicative) forms on Lie n-algebroids, which provide models of symplectic forms.
