Igor Khavkine is a mathematical physicist working on field theory.

This article gives a review and careful re-analysis of covariant phase spaces in local Lagrangian field theory:

This article solves the existence problem of local gauge invariant observables in general relativity by showing that while these do not exist as global functions, they do exist as a sheaf of functions on covariant phase space:
