Regularised Integrals, Sums and Traces: An Analytic Point of View (University Lecture Series, 59, Band 59) - Softcover

Inhaltsangabe

Paycha seeks to clarify some aspects of regularization techniques, which are used to make sense of divergent integrals, discrete sums, or traces. There is nothing groundbreaking here, she says, just a unified perspective based on pedestrian proofs on results scattered in the physics and mathematics literature. Among her topics are the gamma function extended to non-positive integer points, the non-commutative residue as a complex residue, the canonical sum on non-integer order classical symbols, weighted traces, and anomalies of regularized determinants.
