Symmetric stable processes, Fubini’s theorem, and some extensions of the Ciesielski-Taylor identities in law. (English) Zbl 0831.60049

Summary: The Ciesielski-Taylor identities in law between certain functionals of two Bessel processes are generalized with the help of an integration by parts formula for squares of Gaussian processes. In turn, this formula may be extended to stable processes. In fact, an infinite-dimensional version of this formula characterizes stable processes.
