Description
Lattice QCD simulations tend to become stuck in a single topological
sector at fine lattice spacing, or when using chirally symmetric
overlap quarks. In such cases computed observables differ from their
full QCD counterparts by finite volume corrections, which need to be
understood on a quantitative level. We discuss extensions of existing
relations from the literature between correlation functions at fixed
topology and hadron masses at unfixed topology including parity
mixing. Particular focus is put on combining topological finite volume
effects with ordinary finite volume effects. Numerical results for SU(2)
Yang-Mills Theory will be presented
