Length minima for an infinite family of filling closed curves on a one-holed torus

Abstract: We explicitly find the minima as well as the minimum points of the geodesic length functions for the family of filling (hence non-simple) closed curves, $a<sup>2b<sup>n$ ($n\ge 3$), on a complete one-holed hyperbolic torus in its relative Teichm\"uller space, where $a, b$ are simple closed curves on the one-holed torus which intersect exactly once transversely. This provides concrete examples for the problem to minimize the geodesic length of a fixed filling closed curve on a complete hyperbolic surface of finite type in its relative Teichm\"uller space.
