Abstract:
In my talk I will discuss some new features of conformal anomaly and entanglement entropy in the presence of boundaries. The talk is based on recent papers.This is a project to develop a wide expanse of new quantum field theories in 2n-dimensional space-time manifolds. For each 2d qft, there is to be a qft of extended objects in every 2n-dimensional space-time manifold M. The quantum fields live on ``quasi Riemann surfaces'', which are certain spaces of integral (n-1)-currents in M. The notion of integral current comes from Geometric Measure Theory. The quasi Riemann surfaces are complete metric spaces with analytic properties strictly analogous to Riemann surfaces. The new qfts are to be constructed on the quasi Riemann surfaces just as 2d qfts are constructed on ordinary Riemann surfaces. Local fields in space-time are obtained by restricting to small extended objects.
