“Notions weaker than ML-randomness”

Though Martin-L ̈of randomness is the central randomness notion we have discussed, one can address criticisms to the claim that this notion is the appropriate one by considering weaker and stronger randomness notions for sets. We will discuss weaker variants.

"Griffith's theorem and its applications"

In this talk, we will see how all of the machinery we built so far in this seminar, culminates in the statement of Griffith's theorem, which produces a well behaved description of the derivative of the period map in terms of the Kodaira-Spencer map. The power of this result will be explored through concrete examples. In particular, We will make our first encounter with a Torelli theorem.
