is tracial on Ψ0. We also recall the definition of ‘smoothing operators’ OP,. ... Also, theintegral (2.1) vanishes if T is a smoothing operator. Thus, elements in OP can be neglected.

Write e = k op and denote the derived category of left e-modules by.

This can also be written. as S = B(P2,OP(1),σ), where σ Aut(P2) is defined by (λ0 : λ1 : λ2) 7 (λ0 : pλ1 : qλ2).

By [KRS, Lemma 2.9],. (2.9) R(X,Z,L,σ)op = R(X,σ(Z),Lσ1. ,σ1),. where Rop denotes the opposite bimodule algebra in the obvious sense (see
