Abstract:

Let {ξ1,ξ2,…,ξn} be a sequence of indepen
dent and identically distributed U[0,1]distributed random variables. The
 uniform empirical process generated by them is defined as Fn(t)=n-1/2∑
〖DD(〗n〖〗i=1〖DD)〗(I{ξi≤t}-t),〓 0≤t≤1; 〓‖Fn‖=sup〖DD(〗
〖〗0≤t≤1〖DD)〗〖JB(|〗Fn(t)〖JB)|〗.Let U be the Brownian bridge of
 D[0,1] and ‖U‖=sup〖DD(〗〖〗0≤t≤1〖DD)〗〖JB(|〗U(t)〖JB)|
