摘要 | Let X-t = integral(t)(0) f(s)dW(s) + integral(t)(0)gs ds be the anticipating smooth semimartingale and L-t(x) be its generalized local time. In this paper, we give some estimates about the quasi sure property of X-t and its quadratic variation process (X)(t). We also study the fractional smoothness of L-t(x) and prove that the quadratic variation process of L-t(x) can be constructed as the quasi sure limit of the form Sigma Delta(n()L(t)a(n)(i+1) - L(t)a(i)(n))(2), where Delta(n) = (a(i)(n), a(i+1)(n)) is a sequence of subdivisions of vertical bar a, b vertical bar, a(i)(n) = i(b - a)/2(n) + a, i = 0, 1, .... 2(n).
