چکیده
Let BH 0 = fBH 0 (t); t 2 RN+g be a real-valued fractional Brownian sheet. Consider the (N; d) Gaussian random eld BH de ned by BH(t) = (BH 1 (t); : : : ; BH d (t)) (t 2 RN+ ); where BH 1 ; : : : ; BH d are independent copies of BH 0 . In this paper, the existence and joint continuity of the local times of BH are established. Running Title: Local Times of Fractional Brownian Sheets

Local times of multifractional Brownian sheets
Denote by H(t) = (H1(t), . . . ,HN (t)) a function in t ∈ R+ with values in (0, 1) . Let {B(t)} = {B(t), t ∈ R+} be an (N, d)-multifractional Brownian sheet (mfBs) with Hurst functional H(t). Under some regularity conditions on the function H(t), we prove the existence, joint continuity and the Hölder regularity of the local times of {B(t)}. We also determine the Hausdorff dimensions of the lev...
متن کاملProperties of local-nondeterminism of Gaussian and stable random fields and their applications
— In this survey, we first review various forms of local nondeterminism and sectorial local nondeterminism of Gaussian and stable random fields. Then we give sufficient conditions for Gaussian random fields with stationary increments to be strongly locally nondeterministic (SLND). Finally, we show some applications of SLND in studying sample path properties of (N, d)-Gaussian random fields. The...
متن کاملConvergence to Weighted Fractional Brownian Sheets*
We define weighted fractional Brownian sheets, which are a class of Gaussian random fields with four parameters that include fractional Brownian sheets as special cases, and we give some of their properties. We show that for certain values of the parameters the weighted fractional Brownian sheets are obtained as limits in law of occupation time fluctuations of a stochastic particle model. In co...
متن کاملJoint continuity of the local times of fractional Brownian sheets
Let B = {B(t), t∈ RN+} be an (N,d)-fractional Brownian sheet with index H = (H1, . . . ,HN) ∈ (0,1) N defined by B(t) = (B 1 (t), . . . ,B H d (t)) (t∈ R N + ), where B H 1 , . . . ,B H d are independent copies of a real-valued fractional Brownian sheet B 0 . We prove that if d < ∑ N l=1 H l , then the local times of B are jointly continuous. This verifies a conjecture of Xiao and Zhang (Probab...
متن کاملLarge deviations for local times and intersection local times of fractional Brownian motions and Riemann-Liouville processes
In this paper we prove exact forms of large deviations for local times and intersection local times of fractional Brownian motions and Riemann–Liouville processes. We also show that a fractional Brownian motion and the related Riemann–Liouville process behave like constant multiples of each other with regard to large deviations for their local and intersection local times. As a consequence of o...
