چکیده

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 obtain the exact moment generating function for a simple network comprising a few model neurons. Possible directions for the analysis of many neuron networks as well as applications to other neural network models and algorithms are discussed.

Feynman Diagrams and the Quantum Stochastic Calculus

We present quantum stochastic calculus in terms of diagrams taking weights in the algebra of observables of some quantum system. In particular, we note the absence of non-time-consecutive Goldstone diagrams. We review recent results in Markovian limits in these terms. AMS Classification: 81S25, 81T18

Bosonic loop diagrams as perturbative solutions of the classical field equations in φ-theory

Solutions of the classical φ-theory in Minkowski space-time are analyzed in a perturbation expansion in the nonlinearity. Using the language of Feynman diagrams, the solution of the Cauchy problem is expressed in terms of tree diagrams which involve the retarded Green’s function and have one outgoing leg. In order to obtain general tree diagrams, we set up a “classical measurement process” in w...

Summation of diagrams in N = 1 supersymmetric electrodynamics , regularized by higher derivatives .

Summation of diagrams in N = 1 supersymmetric electrodynamics, regularized by higher derivatives. Abstract For the massless N = 1 supersymmetric electrodynamics, regularized by higher derivatives, the Feynman diagrams, which define the divergent part of the two-point Green function and can not be found from Schwinger-Dyson equations and Ward identities, are partially summed. The result can be w...

Application of semi-analytic method to compute the moments for solution of logistic model

The population growth, is increase in the number of individuals in population and it depends on some random environment effects. There are several different mathematical models for population growth. These models are suitable tool to predict future population growth. One of these models is logistic model. In this paper, by using Feynman-Kac formula, the Adomian decomposition method is applied to ...
