Streszczenie
Every multiplicative Lie algebra structure on a group $G$ determines a group homomorphism from the exterior square $G\wedge G$ to $G$. We give a precise characterization of the group homomorphisms $G \wedge G \rightarrow G$ which determine a multiplicative Lie algebra structure on $G$. For certain finite groups, we determine the number of possible images (up to isomorphism) of such structure-defining maps.
