FUNCTION THEORETIC OPERATOR THEORY

Our work in studying dynamical systems stems from a solid background in function theoretic operator theory. This brand of operator theory connects function with operators in a variety of ways. This includes composition operators, multiplication operators, Liouville operators, and Toeplitz operators. Frequently our work in this setting is targeted at characterizing those operators that are compact, bounded, or even densely defined.
