"The quantum random oracle model"
In cryptography, a common task is to reduce the problem of breaking an encryption or digital signature scheme to some underlying hard computational problem. This is similar to how complexity theorists reduce problems to one another to show that they are in the same complexity class.
These reductions can often be established more easily by considering different security models. A common model to employ is called the random oracle model.

“The MarsdenWeinstein Theorem and Some Corollaries”
We will clean up the proof given last talk of the MarsdenWeinstein theorem. We will then prove both the JacobiLiouville theorem and the KrillovKostantSouriau theorem as corollaries. Time permitting, we will introduce multimomentum maps and their existence/uniqueness.

"Positivstellensatz and semipreC*algebras"
A positivstellensatz can loosely be described as a characterisation of elements a in an algebra A that are positive under a certain class of representations. In this talk we review some classical results regarding positive polynomials and then look at a series of Positivstellensatz that can be obtained by using the framework of semipreC*algebras.

"Counting rational points on cubic curves"
We present a new uniform bound for the number of rational points of height at most B on nonsingular cubic curves, which improves upon previous bounds of Ellenberg/Venkatesh and HeathBrown/Testa.

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 centralized within our Office of Indigenous Relations.
