in this paper we initiate the study of real group algebras and investigate some of its aspects.let l1 (g) be a group algebra of a locally compact group g,τ :g →g be a group homeomorphismsuch that τ 2 =τοτ = 1, the identity map, and lp (g,τ ) = { f ∈ lp (g) : fοτ = f } ( p ≥ 1) . in thispaper, among other results, we clarify the structure of lp (g,τ ) and characterize amenability ofl1 (g,τ ) and...

( he absolute risks of a radiation-induced second cancer mong long-term radiotherapy survivors are not large, typcally a few percent in older patients (1–4). Hence the very eal concern, expressed by Kendal et al. (5) in this issue, hat prostate cancer patients may be unduly influenced in heir treatment decision by unbalanced media reports of econd-cancer risks. It is certainly the responsibilit...

The Photoexcited carrier lifetime (τ) and peak to valley transmission difference (ΔTp-v) in direct and indirect band gap crystals has been investigated by the use of single beam open and closed aperture z-scan technique using frequency doubled Nd:YAG laser. The peak to valley transmission difference (ΔTp-v) is found to be of the order of 10-2 in case of direct band gap crystals and of the order...
