We consider a branching particle system where an individual particle gives birth to a random number of offspring at the place where it dies. The probability distribution of the number of offspring is given by pk , k = 2, 3, …. The corresponding branching process is related to the semilinear partial differential equation for x ∈ ℝ d , where A is the infinitesimal generator of a multiplicative semigroup and the pk s, k = 2, 3, …, are nonnegative functions such that We obtain sufficient conditions… 
Existence and probabilistic representation of the solutions of semilinear parabolic PDEs with fractional Laplacians
We obtain existence results for the solution u of nonlocal semilinear parabolic PDEs on Rd with polynomial nonlinearities in (u,∇u), using a tree-based probabilistic representation. This
Perturbative Expansion Technique for Non-Linear FBSDEs With Interacting Particle Method
In this paper, we propose an efficient Monte Carlo implementation of a non-linear FBSDE as a system of interacting particles inspired by the idea of the branching diffusion method of McKean. It will
Stability of a Nonlinear Equation Related to a Spatially-inhomogeneous Branching Process
Consider the nonlinear equation $$\frac{\partial}{\partial t}u(x,t)=\Delta_\alpha u (x, t) + a(x) \sum\limits_{k=2}^{\infty} pk^{{u^k}} (x, t)+(p0 + p1 u(x, t))\phi(x), x\in \mathbb{R}^d,$$
A fully nonlinear Feynman-Kac formula with derivatives of arbitrary orders
We present an algorithm for the numerical solution of nonlinear parabolic partial differential equations with arbitrary gradient nonlinearities. This algorithm extends the classical Feynman-Kac
Numerical evaluation of ODE solutions by Monte Carlo enumeration of Butcher series
The Monte Carlo scheme allows for the direct numerical evaluation of an ODE solution at any given time within a certain interval, without iteration through multiple time steps, and it does not require the truncation of Taylor series.

On Branching Markov Processes
In this paper we give a definition of branching Markov processes in terms of a property of the semi-group of Markov processes and describe several equivalent formulations. Our definition is a
Length of Galton–Watson trees and blow-up of semilinear systems
By lower estimates of the functionals 𝔼[e S t K t N t ], where S t and N t denote the total length up to time t and the number of individuals at time t in a Galton-Watson tree, we obtain sufficient
Fundamental Equations of Branching Markov Processes
We have given in the previous paper 2 a definition of branching Markov processes and discussed some fundamental properties of them. Here we shall treat several fundamental equations which describe
