On the formal modular Invariants of binary Forms
Existence, uniqueness, and regularity for functions of least gradient.
Nonfibered knots and representation shifts
A conjecture of [swTAMS] states that a knot is nonfibered if and only if its infinite cyclic cover has uncountably many finite covers. We prove the conjecture for a class of knots that includes all knots of genus 1, using techniques from symbolic dynamics.
