The geometri representation theory of these algebras has been studied in [Lu1, Lu2, Lu3 and fundamental re-sults have appeared in [HO, Op. ... The following proposition provides a graded He ke analogue of the results in [Ka,Proposition 1.20 and [Ka,

p is a p-complete, nilpotent space and π1(BG. p )= G/Op(G). ... HBG = HBNG(D) = HB(NG(D)/Op′NG(D)) = HBDNG(D)/CG(D). Proof. See Swan [209].

In the second half of this text we study bounded linear op-erators on the generalised sequence space p(ZN , U ), where p [1, ] and U issome complex Banach space. ... Collective Compactness. In the mid 1960’s Anselone and co-workers (see[3] and the

Typically, an operator in Op hS(q,p,p′) with p < 0 and p′ < 0 is compact. ... 12 (2.35). is an h-pseudodifferential operator. More precisely it belongs to Op hS(0,0,0).

Inother words, it is conjectured that for a ‘generic’ selfadjoint second-order elliptic op-erator with periodic coefficients on Rd each of the spectral gap’s endpoints is a unique(modulo
