量子射影空间上的Dirac算子

Dirac Operators on Quantum Projective Spaces

Francesco D'Andrea, Ludwik Dabrowski

摘要:

本文构造了一类自伴算子D_N,它与量子射影空间CP_q(l)的坐标代数具有紧预解式和有界预解式,对任意l>1和0<q<1.它们提供0^+维等变偶谱三元组。如果l是奇数且N=(l+1)/2,则谱三元组是具有KO-维数2l mod 8的实数。

英文摘要:

We construct a family of self-adjoint operators D_N which have compact resolvent and bounded commutators with the coordinate algebra of the quantum projective space CP_q(l), for any l>1 and 0<q<1. They provide 0^+ dimensional equivariant even spectral triples. If l is odd and N=(l+1)/2, the spectral triple is real with KO-dimension 2l mod 8.
