“Characterizations of operator-valued Hardy spaces.”

I will introduce the operator-valued Hardy spaces studied by Tao Mei, and show that the Poisson kernel in Mei’s definition of these spaces can be replaced by any reasonable test function. An important example of such test function is given by positive-order Riesz potential of the Poisson kernel.

“Divisors and Blow-ups”

We will introduce divisors on complex manifolds as well as the notion of the degree of a divisor and the relationship between divisors and the Picard group. Afterwards, we will discuss B ́ezout’s theorem and blow-ups along complex submanifolds.

“R.i.c.e. relations”

This week we start chapter 2 and introduce some Relatively intrinsic notions. Basically we discuss R.i.c.e. (relatively intrinsic computably enumerable) relations and give some examples. Our goal is to prove a characterization theorem for R.i.c.e. relations.

“The Schafke-Singer theorem, I.”

We give an overview of a recent result of Schafke and Singer on power series that are well- behaved with respect to two ”orthogonal” operators. We discuss possible extensions of this to other complete local rings and approaches for obtaining these extensions.

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 promised 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 centralized within our Indigenous Initiatives Office.
