Vector supersymmetry in topological field theories

We present a simple derivation of vector supersymmetry transformations for topological field theories of Schwarz- and Witten-type. Our method is similar to the derivation of BRST-transformations from the so-called horizontality conditions or russian formulae. We show that this procedure reproduces in a concise way the known vector supersymmetry transformations of various topological models (in particular of general relativity viewed as a topological-like model) and we use it to obtain some new transformations of this type for 4d topological YM-theories in different gauges.
