A Laurent expansion for regularised integrals of holomorphic symbols
Sylvie Paycha, Simon Scott
For a holomorphic family of classical pseudodifferential operators on a closed manifold we give exact formulae for all coefficients in the Laurent expansion of its Kontsevich-Vishi…

Weighted trace cochains; a geometric setup for anomalies
Sylvie Paycha
We extend formulae which measure discrepancies for regularized traces on classical pseudodifferential operators to regularized trace cochains, regularized traces corresponding to 0…
