Exact analytic moments and ergodicity properties are derived for occupation times in Gaussian and fractional Brownian motions, with universal features identified via infinite ergodic theory and confirmed by simulations.
erf a− ⟨x(τ)⟩p 2C(τ, τ) ! + erf a+⟨x(τ)⟩p 2C(τ, τ) !# (D2) where the integration constant is zero provided thatI 2(a= 0) = 0. Finally, Eq. (48) has the form ⟨Ta(t)⟩= 1 2 Z t 0
