We investigate both the hyperbolic action and the determinant ratio action designed to. x the topological charge on the lattice. We show to what extent topology is fixed depending on the parameters of these actions, keeping the physical situation fixed. At the same time the agreement between different definitions of topological charge - the field theoretic and the index definition - is directly correlated to the degree topology is fixed. Moreover, it turns out that the two definitions agree very well. We also study finite-volume effects arising in the static potential and related quantities due to topology fixing.
