The noise term represents the random fluctuations that are present in the system and is modeled by a Wiener process. The stochastic dynamical phi(4) equation is a powerful tool for modeling the behavior of complex systems that exhibit randomness and nonlinearity. It has a wide range of applications in physics, chemistry, biology, and finance. Our goal of this paper is to use the new extended direct algebraic method to find the stochastic traveling wave solutions of the dynamical phi(4) equation. We explore the new trigonometric, hyperbolic, and rational functions using the new extended direct algebraic method. Furthermore, we use Matlab to plot 3D surfaces of exact solutions to show how multiplicative noise affects the solutions to the stochastic dynamical phi(4) equation.eninfo:eu-repo/semantics/openAccess(3 + 1) dimensional stochastic dynamical phi(4) equationStochastic traveling wave solutionsNew extended direct algebraic methodMultiplicativeAnalyzing multiplicative noise effects on stochastic dynamical ?4 equation using the new extended direct algebraic methodArticle97185203N/AWOS:001233267300001Q12-s2.0-8519051451510.1016/j.aej.2024.04.011
