The paper deals with various centering problems for probability measures onfinite dimensional vector spaces. We show that for every such measure thereexists a vector $h$ satisfying $\mu*\delta(h)=S(\mu*\delta (h))$ for eachsymmetry $S$ of $\mu$, generalizing thus Jurek's result obtained for fullmeasures. An explicit form of the $h$ is given for infinitely divisible $\mu$.The main result of the paper consists in the analysis of quasi-decomposable(operator-semistable and operator-stable) measures and finding conditions forthe existence of a `universal centering' of such a measure to a strictlyquasi-decomposable one.
