Local Non-Archimedean Dynamical Systems in Two Variables:  In joint work with Steven Spallone, we consider locally-convergent analytic mappings over K^{2}, where K is a non-archimedean field. Our goal is to construct conjugations to polynomial normal forms. In particular, our focus is on so-called `Semi-hyperbolic' dynamical systems. We give a full formal and analytic classification, building off earlier formal work in the complex plane, and analytic work in the one-dimensional non-archimedean case. The results are in stark contrast to the complex case.
