= Wiener series
{wiki=Wiener_series}
The Wiener series is a mathematical concept used primarily in the field of stochastic processes, particularly in the study of Brownian motion and other continuous-time stochastic processes. It provides a way to represent certain types of stochastic processes as an infinite series of orthogonal functions. \#\#\# Key Features of Wiener Series: 1. **Representation of Brownian Motion**: The Wiener series is often used to express Brownian motion (or Wiener process) in terms of a stochastic integral with respect to a Wiener process.
