%0 Journal Article %T The $\frac 43$-variation of the derivative of the self-intersection Brownian local time and related processes %A Yaozhong Hu %A David Nualart %A Jian Song %J Mathematics %D 2012 %I arXiv %X In this paper we compute the $\frac 43$-variation of the derivative of the self-intersection Brownian local time $\gamma_t=\int_0^t \int_0^u \delta '(B_u-B_s)dsdu\,, t\ge 0$, applying techniques from the theory of fractional martingales. %U http://arxiv.org/abs/1203.1368v1
