Functional-Integral Based Perturbation Theory for the Malthus-Verhulst Process
We apply a functional-integral formalism for Markovian birth and death processes to determine asymptotic corrections to mean-field theory in the Malthus-Verhulst process (MVP). Expanding about the stationary meanfield solution, we identify an expansion parameter that is small in the limit of large mean population, and derive a diagrammatic expansion in powers of this parameter. The series is ev...
متن کاملMultivariate Integral Perturbation Techniques - I (Theory)
We present a quasi-analytic perturbation expansion for multivariate N dimensional Gaussian integrals. The perturbation expansion is an infinite series of lower-dimensional integrals (one-dimensional in the simplest approximation). This perturbative idea can also be applied to multivariate Student-t integrals. We evaluate the perturbation expansion explicitly through 2 order, and discuss the con...
متن کاملPerturbation Method for a Non-convex Integral Functional
We consider a model problem of minimization of an integral functional over Lipschitz curves. In order to ensure existence of minimum for some perturbed function, a novel variational principle is adapted.
متن کاملPath Integral Density Functional Theory
A new method ( PI-DFT ) which combines path integrals and density functional theory is proposed as a pathway to many fields of physics. Within path integral theory it is possible to construct particle densities without explicitly calculating individual wave functions. These densities can directly be used as an input to energy density functionals. Thus our method makes full use of the theorem of...
متن کاملT-Stability Approach to the Homotopy Perturbation Method for Solving Fredholm Integral Equations
The homotopy perturbation method is a powerful device for solving a wide variety of problems arising in many scientific applications. In this paper, we investigate several integral equations by using T-stability of the Homotopy perturbation method investigates for solving integral equations. Some illustrative examples are presented to show that the Homotopy perturbation method is T-stable for s...
