Certain Applications of the Burnside Rings and Ghost Rings in the Representation Theory of Finite Groups (II)
K. K. Nwabueze and F. Van Oystaeyen
Using the Burnside ring theoretic methods a new setting and a complete description of the Artin exponent $A(G)$ of finite $p$-groups was obtained in a previous article of the first-named author. In this paper, we compute $A(G)$ for any finite group $G$ – hence providing the global version of that result.
