Worldline Green functions for arbitrary Feynman diagrams

Relation between worldline Green functions for scalar two-loop diagrams

We discuss a relation between two-loop bosonic worldline Green functions which are obtained by Schmidt and Schubert in two different parametrizations of a twoloop worldline. These Green functions are transformed into each other by some transformation rules based on reparametrizations of the proper time and worldline modular parameters. 1 Fellow of the Danish Research Academy, [email protected]...

Feynman Diagrams for Stochastic Neurodynamics

We present here a method for the study of stochastic neurodynamics in the framework of the Neural Network Master Equation proposed by Cowan. We consider a model neural network composed of two{ state neurons subject to simple stochastic kinetics. We introduce a method based on Feynman diagrams to compute the moment generating function of such a network. We show that the method enables us to obta...
