A Combinatorial Perspective on Quantum Field Theory by Karen Yeats

By Karen Yeats

This publication explores combinatorial difficulties and insights in quantum box idea. it isn't complete, yet particularly takes a journey, formed via the author’s biases, via many of the very important ways in which a combinatorial viewpoint may be dropped at undergo on quantum box thought. one of the results are either actual insights and fascinating mathematics.

The e-book starts off via considering perturbative expansions as types of producing capabilities after which introduces renormalization Hopf algebras. the remaining is damaged into elements. the 1st half appears at Dyson-Schwinger equations, stepping steadily from the only combinatorial to the extra actual. the second one half seems to be at Feynman graphs and their periods.

The flavour of the publication will attract mathematicians with a combinatorics heritage in addition to mathematical physicists and different mathematicians.
