Abstract. Let K be a locally compact hypergroup with left Haar

measure and let P1

(K) = {f ∈ L1

(K) : f ≥ 0, kfk1 = 1 }. Then

P1

(K) is a topological semigroup under the convolution product ...

The Euclidean group (IRn, +) where n 2 IN, plays a key role in harmonic analysis.

If we consider the Lebesgue measure dμIRn(x) as the Haar measure of this

group then 1

2n dμIRn(x2) = dμIRn(x). In this ...
