Local and uniform moduli of continuity of chi–square processes

Abstract

Let { η i ( t ) , t ∈ [0 , 1] } ki =1 be independent copies of η = { η ( t ) , t ∈ [0 , 1] } , a mean zero continuous Gaussian process. Let This paper shows how exact local (at 0) and uniform moduli of continuity (on [0,1]) of Y k can be obtained from the exact local and uniform moduli of continuity of η .
