Abstract

The speaker considers the problem of identifying a unitary connection \nabla on a vector bundle, up to gauge equivalence, from the Dirichlet-to-Neumann map of the connection Laplacian \nabla^*\nabla. One possible approach is through the construction of special Complex Geometric Optics solutions and a further reduction of the problem to an X-ray transform. The speaker also considers another approach in the Yang-Mills connections setting, based on picking a special gauge, in which the Yang-Mills equations become elliptic and using a unique continuation principle for elliptic systems for identification near the boundary.
