Abstract:
It is a classical problem to give explicit formulae for characteristic functions of quadratic functionals of Brownian motions, and there are many works on this topic. Ikeda-Kusuoka-Manabe [4], [5] gave a new idea to solve this problem and showed some results from which almost all known results followed. In this paper the authors extend their results based on their idea.

Keywords: Brownian motion, quadratic functional, characteristic function.
