%0 Journal Article %T Amenability of the Algebras R(S), F(S) of a Topological Semigroup S %A Massoud Amini %A Alireza Medghalchi %J Mathematics %D 2002 %I arXiv %X For a locally compact Hausdorff semigroup S, the $L^\infty$ representation algebra R(S) was extensively studied by Dunkl and Ramirez. The Fourier-Stieltjes algebra F(S) of a topological semigroup was studied by Lau. The aim of this paper is to investigate these two algebras and study the amenability of them with respect to the structure of S. %U http://arxiv.org/abs/math/0205255v1
