Karthik Bharath: The shape of functional data

1:00pm, CM107

Data in the form of functions contain phase variability, which quite often is considered as nuisance. One way to remove the phase/warping variation is to align the functions to a common template by warping their domains. Alternatively, one can ignore phase variation altogether and consider only the shape of each function: an equivalence class of functions that are related to it through the warping of its domain.

I will discuss the structure of the shape space of real-valued functions on an interval as a quotient space under the action of the warping group, and describe the difficulties involved in defining probability distributions on such shape spaces. Such a perspective elucidates on conditions that ensure identifiability of signal plus noise models for functional data, and also provides a way to control small-ball probabilities of functional predictors affecting asymptotic properties of kernel-based estimators of functional regression models.

This is joint work with Ian Jermyn (Durham).

Saghar Hosseinisemnani: Exact Solution of 2D Yang-Mills Theory

5:00pm, OC218

The 2D Yang-Mills theory is an example of a quantum field theory which can be solved exactly without resorting to perturbation theory. ‘Solving’ the theory means finding an exact expression for the partition function of the theory on a Riemann surface Σ of genus g and area A. The free 2D Yang-Mills theory partition function only depends on A and g, and not the special geometry of Σ, so in the zero area limit it is a topological quantum field theory. I will calculate the partition function by first considering the theory on a cylinder in the Hamiltonian formulation. Then, once we have the partition function on a cylinder, I will use the ‘gluing rule’ to find the partition function on a Riemann surface of genus g.
