# Algebra and Topology Seminar

## Contact

The Algebra and Topology seminar invites speakers from a broad spectrum of areas, including algebraic and differential geometry, algebraic topology, low-dimensional topology, representation theory, quantum algebra, and number theory.

There is also a Google calendar for the seminar, which typically lists scheduled speakers in advance of their posting here.

Speaker: Felipe Voloch (U. of Canterbury)

The task of factoring polynomials modulo a prime has a satisfactory, usually efficient, solution which depends on random choices and can be slow if we are v

Speaker: Joan Licata (ANU/MSI)

Many approaches to studying 3-manifolds start by cutting the manifold into simpler pieces. In the context of contact geometry, I'll describe how to decompo

In a 2003 paper Bondal and Van den Bergh proved that, if X is a scheme smooth over a field k, then the category D^b(Coh X) is strongly generated.

Speaker: Ralph Buchholz (ANU)

We consider the problem of finding triangles with rational sides medians and area. We see how far we can get using the theory of curves and surfaces.
