We analyzed the constraint structure of the Einstein-Hilbert first-order action in two dimensions using the Hamilton-Jacobi approach. We were able to find a set of involutive, as well as a set of non-involutive constraints. ...

This is the first paper in a two-part series devoted to studying the Hausdorff dimension of invariant sets of non-uniformly hyperbolic, non-conformal maps. Here we consider a general abstract model, that we call piecewise ...

One-loop two-point functions play an important role in quantum field theories, being one of the primary divergent Feynman graphs that calls for regularization and renormalization procedures. These well-known functions are ...
