Conjectured semi-finite spectral triple in the continuum limit
Conjectured semi-finite spectral triple in the continuum limit
Let be the underlying 3-manifold, let and be the continuum limits of the corresponding graph-level structures, and let be the limiting operator. Let be the Clifford algebra of the cotangent space of the connection space, and let be the continuum algebra whose trace is induced by matrix traces on .
Continuum spectral-triple conjecture. The Kasparov module
is a semi-finite spectral triple with respect to the trace over and the trace over induced by matrix traces over .
Together with the preceding conjecture, this would yield the desired semi-finite spectral triple in the continuum limit. The source does not analyze the existence of or the behavior of its spectrum, so the claim remains open.
