Let A be an artin algebra and e ∈ A an idempotent with add(eAA) = add(D(AAe)). Then a projective resolution of AeeAe gives rise to tilting complexes {P(l) • } l¿1 for A, where P(l) • is of term length l + 1. In particular, if A is self-injective, then End K(Mod-A) (P(l) • ) is self-injective and has

Bypassing much theory from integral geometry, we construct an elementary measure on a space whose elements can represent rank k orthogonal projections in N . By replacing the Grassmannian G N k with a simple product space k j=1 S N-1 we are able to reproduce certain important features of the nontriv
