The Prime Decomposition Theorem for 3-Manifolds

Ojas Mittal
((Mathematical Institute University of Oxford))
Abstract

A 3-manifold is a space which locally looks like R^3. A major theme in 3-manifold Topology is to understand and classify 3-manifolds. Given two compact 3-manifolds M_1,M_2 we can form another 3-manifold by taking what’s called the “connect sum” of M_1 and M_2. Under this operation, 3-manifolds can be decomposed uniquely into prime pieces just like the integers can be decomposed uniquely as a product of primes. We will discuss this prime decomposition theorem for 3-manifolds while also giving a wide variety of examples.

A FBSDE construction of the sine-Gordon EQFT

Sarah-Jean Meyer
Abstract

I will present a construction and characterization of the (massive) sine-Gordon EQFT up to 6π in the full space.  The construction relies on a systematic study of the renormalization flow equation and a forward backward stochastic differential equation (FBSDE) which give good control of the EQFT and allows to derive various additional properties.

The past isn't a foreign country on social media; it's an eternal present.

So we made Josh Bull take his exams all over again.
