The -variation of the divergence integral with respect to the fractional Brownian motion for and fractional Bessel processes

We study the 1 / H -variation of the indefinite integral with respect to fractional Brownian motion for H > 1 2 , where this integral is defined as the divergence integral in the framework of the Malliavin calculus. An application to the integral representation of Bessel processes with respect to fractional Brownian motion is discussed.
