This book develops the unified combinatorial framework behind these examples, starting with the simplest mathematically, and working up to the Fock space setting for quantum fields. Emphasizing ideas from combinatorics such as the role of lattice of partitions for multiple stochastic integrals by WallstromRota and combinatorial species by Joyal, it presents insights coming from quantum probability. It also introduces a ''field calculus'' which acts as a succinct alternative to standard Feynman diagrams and formulates quantum field theory (cumulant moments, DysonSchwinger equation, tree expansions, 1-particle irreducibility) in this language.

The text is highly accessible thanks to the careful choice of topics and the systematic use of elegant combinatorial and algebraic methods. This makes the book suitable for graduate level teaching and self-study. I highly recommend it as a timely addition to the classical literature on quantum probability.'
