Algebraic Versus Spectral Torsion
Ludwik DÄ browski, Yang Liu, Sugato Mukhopadhyay
We relate the recently defined spectral torsion with the algebraic torsion of noncommutative differential calculi on the example of the almost-commutative geometry of the product o…

Spectral Torsion
Ludwik DÄ browski, Andrzej Sitarz, PaweÅ Zalecki
We introduce a trilinear functional of differential one-forms for a finitely summable regular spectral triple with a noncommutative residue. We demonstrate that for a canonical spe…
