Question:
Exercise 12.12 Consider a Brownian motion {X(t)} with drift μ and diffusion coefficient σ defined on the interval [0, a], where the boundaries 0 and a > 0 are absorbing. Using the transformation (12.15) and the result (10.19)
with N = a/Δx, show that the transition density function a(x, y, t) of the Brownian motion is given by
