Analytic torsion for graphs Analytic torsion is a functional on graphs which only needs linear algebra to be defined. In the continuum it corresponds to the Ray-Singer analytic torsion. We have formulas for analytic torsion if t...

Analytic torsion for graphs is the new invariant in town for topological machine learning. First time I see a super determinant in my life.
