Stochastic diagrams and Feynman diagrams [PDF]
Nuclear Physics B, 1985 Abstract We study the relationship between ordinary perturbation theory and perturbation theory obtained from stochastic quantization. We give a simple proof that, except in gauge theories, the several stochastic diagrams of a given topology are together equivalent to the corresponding Feynman diagram.

Communications in Mathematical Physics, 1978 The authors describe their method for counting planar Feynman diagrams of quantum field theory. Mathematicians who are not familiar with the current jargon of quantum field theory are likely to find this paper rather difficult to follow. In order to demonstrate the usefulness of their method, the authors calculate the ground state energy of a system of

, 2020 In this paper, we investigate diagrams, namely functors from any small category to a fixed category, and more particularly, their bisimilarity. Initially defined using the theory of open maps of Joyal et al., we prove several equivalent characterizations: it is equivalent to the existence of a relation, similar to history-preserving bisimulations for ...

Signata, 2020 We will examine two recent site-specific dance creations: Hofesh Schechter’s Coda and Saburo Teshigawara’s Pointed Peak. The description of the experience of these performances for an “ethnographer” viewer will lead us to use the semiotic theories of ...
