It is also the notation used in publications on numerical methods for solving stochastic differential equations. The mathematical formulation treats this complication with less ambiguity than the physics formulation. This equation should be interpreted as an informal way of expressing the corresponding integral equation.

This is so because the increments of a Wiener process are independent and normally distributed. The stochastic process X t is called a diffusion process , and satisfies the Markov property. There are two main definitions of a solution to an SDE, a strong solution and a weak solution. Both require the existence of a process X t that solves the integral equation version of the SDE. A weak solution consists of a probability space and a process that satisfies the integral equation, while a strong solution is a process that satisfies the equation and is defined on a given probability space.

An important example is the equation for geometric Brownian motion.

When the coefficients depends only on present and past values of X , the defining equation is called a stochastic delay differential equation. As with deterministic ordinary and partial differential equations, it is important to know whether a given SDE has a solution, and whether or not it is unique. Its general solution is. In supersymmetric theory of SDEs, stochastic dynamics is defined via stochastic evolution operator acting on the differential forms on the phase space of the model. In this exact formulation of stochastic dynamics, all SDEs possess topological supersymmetry which represents the preservation of the continuity of the phase space by continuous time flow.

The spontaneous breakdown of this supersymmetry is the mathematical essence of the ubiquitous dynamical phenomenon known across disciplines as chaos , turbulence , self-organized criticality etc. The theory also offers a resolution of the Ito—Stratonovich dilemma in favor of Stratonovich approach.
