Abstract

The class of subexponential distributions S is considered by F(0) = 0, 1 - F(2)(x) ~ 2(1 - F(x)) as x ® ¥. In this paper we consider a subclass of S for which the relation 1 - F(2)(x) - 2(1 - F(x)) + (1 - F(x))2 = o(a(x)) as x ® ¥ holds, where a is a positive function satisfying a(X) = o(1 - F(x)) (x ® ¥).
