“Applications of order isomorphisms of C*algebras”
We will review known results about order isomorphisms of C*algebras, and will describe some applications to complete positivity of maps and a generalization of the Choi matrix. (This is joint work with Vern Paulsen.) Then we will describe some applications to quantum information theory.

We will continue with our discussion of the path integral, and derive the Feynman rules for the phi4 theory.

"Dynamical Analogue of Results by BombieriMasserZannier and Habegger"
First, we briefly explain how results and questions in diophantine geometry give rise to interesting problems in arithmetic dynamics. Then we focus on dynamical analogue of the following results by
Bombieri, Masser, Zannier and Habegger.

“Relative Randomness and van Lambalgen’s Theorem  Part 2”
We continue last week’s presentation and present a proof of van Lambalgen’s Theorem. To conclude this subsection, we also remark on some of the consequences of this result. Time per mitting, we also discuss some applications of relativized randomness to lowness and highness.

We will describe a correspondence of ideals of R with ideals of the ring of fractions Q(R) in the case where R is noetherian. There will also be examples.

“A higher rank Selberg sieve and applications”
We present a general higher rank Selberg sieve and apply it to various questions in number theory. In particular, we improve upon a result of HeathBrown on almost prime ktuples. This is joint work with Professor Ram Murty.

“Xiaos Conjecture on Canonically Fibered Surfaces”
In 1988, Gang Xiao proposed a list of open problems on algebraic surfaces. Many of these remain open to this day. One of the problems concerns the maximal relative genus of a canonically fibered surface. In this talk, I will talk about my proof of this conjecture.

“Notions weaker than MLrandomness”
Though MartinL ̈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 KodairaSpencer map. The power of this result will be explored through concrete examples. In particular, We will make our first encounter with a Torelli theorem.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is coordinated within our Office of Indigenous Relations.
