Abstract: 

The first one of the algebraic geometry seminars will be about deformation of complex structure of CY  manifolds.I will start by giving the definition of CY manifold and universal  deformation. After explaining some properties of these objects I will  state and show the main steps of the proof of Bogomolov-Tian-Todorov  (BTT) unobstructedness theorem.Thanks to BTT theorem, we have smoothness of the base space of the  universal deformation of CY without global (nontrivial) vector fields.
