Title: Uniformly continuous and Lipschitz reducibilities on ultrametric Polish spaces
Abstract: We analyze the reducibilities induced by, respectively, uniformly continuous, Lipschitz, and nonexpansive functions on arbitrary ultrametric Polish spaces, and give sufficient and necessary (topological) conditions on such spaces for the corresponding degree-structures being well-behaved. This is joint work with Philipp Schlicht.
