چکیده

Two forms of uncertainty are identified to be associated with dynamical systems, which randomness and belief degree. The uncertain stochastic differential equation (USDE) is used describe systems driven simultaneously by human (belief degree). In this paper, the Euler-Maruyama method for solving USDEs examined. solve a stock pricing problem results compared those Runge Kutta order 4. yields lower prices, while prices from proved converge faster analytical method. At α = 0.5 where ∈ (0, 1), USDE reverts equation, component eliminated, showing that indeed hybrid equation. Key words: Euler-Maruyama, price, contour process.

Computational Method for Fractional-Order Stochastic Delay Differential Equations

Dynamic systems in many branches of science and industry are often perturbed by various types of environmental noise. Analysis of this class of models are very popular among researchers. In this paper, we present a method for approximating solution of fractional-order stochastic delay differential equations driven by Brownian motion. The fractional derivatives are considered in the Caputo sense...

Convergence of the Euler-Maruyama method for stochastic differential equations with Markovian switching

Stochastic differential equations with Markovian switching (SDEwMSs), one of the important classes of hybrid systems, have been used to model many physical systems that are subject to frequent unpredictable structural changes. The research in this area has been both theoretical and applied. Most of SDEwMSs do not have explicit solutions so it is important to have numerical solutions. It is surp...

Convergence rates of the truncated Euler-Maruyama method for stochastic differential equations

Influenced by Higham, Mao and Stuart [9], several numerical methods have been developed to study the strong convergence of the numerical solutions to stochastic differential equations (SDEs) under the local Lipschitz condition. These numerical methods include the tamed Euler–Maruyama (EM) method, the tamed Milstein method, the stopped EM, the backward EM, the backward forward EM, etc. Recently,...
