Abstract
This paper develops a recursion formula for the conditional moments of
the area under the absolute value of Brownian bridge given the local time
at 0. The method of power series leads to a Hermite equation for the generating function of the coefficients which is solved in terms of the parabolic
cylinder functions. By integrating out the local time variable, this leads to
an integral expression for the joint moments of the areas under the positive and negative parts of the Brownian bridge.
