Systematic Analytic Regularization in $φ^{4}$ and Yukawa Theories

Jarryd Bath, W. A. Horowitz

We introduce a novel regularization scheme: Systematic Analytic Regularization (SAR). SAR regularizes a theory at the level of the action by analytically continuing the power of th…

From Exact Space-Time Symmetry Conservation to Automatic Mesh Refinement in Discrete Initial Boundary Value Problems

Alexander Rothkopf, W. A. Horowitz, Jan Nordström

In this contribution we present recent developments in the formulation and solution of Initial Boundary Value Problems (IBVPs). Building upon a modern variational action formulatio…

Hamilton Revised: The Action Principle for Initial Value Problems

W. A. Horowitz, A. Rothkopf

We present the variational action principle for initial value problems in classical, conservative-force point particle mechanics. We rigorously derive this formulation by taking th…
