Abstract

In this paper, under suitable assumptions on the Gaussian process $$G=\lbrace G_t,\,t\ge 0\rbrace $$ G = { G t , t ≥ 0 } , we establish results on uniform convergence in probability and in law stably for the realized power variation of the Riemann–Stieljes integral $$Z_t=\int _0^t u_s \text {d}Y_{s,G}^{(1)}$$ Z t = ∫ 0 t u s d Y s , G ( 1 ) with respect to $${Y_{t,G}^{(1)}}=\int _0^t \text {e}^{-s} \text {d}G_{a(s)}$$ Y t , G ( 1 ) = ∫ 0 t e - s d G a ( s ) , where u is a process of finite q-variation with $$q
