Gao, Fu Qing, Laws of the iterated logarithm for locally square integrable martingales, Acta mathematica Sinica. English series (Print) , 25(2), 2009, pp. 209-222
Three types of laws of the iterated logarithm (LIL) for locally square integrable martingales with continuous parameter are considered by a discretization approach. By this approach, a lower bound of LIL and a number of FLIL are obtained, and Chung LIL is extended.
