Abstract
We study the spectral geometry of the quantum projective plane, a deformation of the complex projective plane CP2, the simplest example of spinc manifold which is not spin. In particular, we construct a Dirac operator D which gives a 0+ summable triple, equivariant under Uq(su(3)). The square of D is a central element for which left and right actions on spinors coincide, a fact that is exploited to compute explicitly its spectrum.File in questo prodotto:
