"Ricci flow beyond nonnegative curvature conditions"
We generalize most of the known Ricci flow invariant nonnegative curvature conditions to less restrictive negative bounds that remain sufficiently controlled for a short time.

"Introduction to Positive Logic II"
We continue our investigation of positive logic. I will define a new notion of the space of types and I will convince you that it is the right notion.

"Branching Processes, Martingales, Kingman’s Subadditive Ergodic Theorem, and some applications, Part IV: Kingman’s Subadditive Ergodic Theorem"
And now for something completely different. We leave GaltonWatson processes behind and talk a bit about Birkhoff’s Ergodic Theorem and Fekete’s Lemma. The latter states that a_{n}/n converges if a_{n} is a subadditive sequence and Kingman’s subadditive ergodic theorem provides a dynamical / random analogue.

"ParsellVinogradov systems in higher dimensions"
I will present a few results on counting the numbers of integer solutions of ParsellVinogradov systems in higher dimensions. A few techniques from harmonic analysis are crucial in our approach. They are BrascampLieb inequalities, multilinear Kakeya inequalities, induction on scales, etc.

"A finite pointed group with no finite basis (part 2)"
We'll continue to go over the construction of Roger Bryant. Hopefully, we'll finally see the group P, and argue that every (n1)generated subalgebra of Q_n is in HSP(P).
