摘 要: Let p>1 and G be a discrete group. The reduced group Lp-operator algebra is generated by the left regular representation of G on lp(G). When p=2, this algebra is the reduced group C*-algebra. It is well known that the amenability of the group G is equivalent to the nuclearity of the reduced group C*-algebra. G. An, J.-J. Lee and Z.-J. Ruan introduced the p-nuclearity for Lp-operator algebras and they show that the p-nuclearity for the reduced group Lp-operator algebra of G follows from the amenability of G. The converse is unknown and it is an open problem raised by N. C. Phillips. In this talk, we will review the classical results for the amenability and nuclearity for the C*-algebras. Then we give some new developments to the converse of G. An, J.-J. Lee and Z.-J. Ruan’s result.
