introduction

  • scaling limit of a random walk on a two dimensional grid
    • the limit of random walk as the time and space increments go to zero.
  • Mandelbrot conjecture

 

 

heat equation and Brownian motion

 

 

Wiener process

  • synonym with Brown motion
  • example of a Levy process

 

 

 

Mandelbrot conjecture
