Harmonic Analysis on Double Coset Spaces

Massoud Amini, Alireza Medghalchi

We prove the existance and uniqueness of quasi-invariant measure on double cost space $K \ G / H$ and study the Fourier and Fourier-Stieltjes algebras of these spaces.

Amenability of the Algebras R(S), F(S) of a Topological Semigroup S

Massoud Amini, Alireza Medghalchi

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 topolo…

Fourier Algebras On Topological Foundation *-Semigroups

Massoud Amini, Alireza Medghalchi

We introduce the notion of the Fourier and Fouier-Stieltjes algebra of a topological *-semigroup and show that these are commutative Banach algebras. For a class of foundation semi…
