....fW n ( n 1g is a non negative martingale sequence and hence converges w.p. 1 to a random variable W ( Furthermore, for 2 E(0) P (W ( 0jZ (0) ffi 0 ) 1 or q according as E(W 1 ( log W 1 ( jZ (0) ffi 0 ) 1 or 1: 2 The details of proof can be found in Biggins (see [28 ]) where the assumption m( 1 for all is considerably reduced. A conceptual proof of the above result along the lines of the one in [49] has been established by Lyons (see [50] Biggins [30] also considers uniform convergence of W n ( to W ( for in some compact set. Biggins and ....

Biggins (1977) has determined when W (ff) is nontrivial: Biggins Theorem. Suppose that ff 2 R is such that m(ff) 1 and m 0 (ff) exists and is finite. Then the following are equivalent: i) P[W (ff) 0] q; ii) P[W (ff) 0] 1; iii) E[W (ff) 1; iv) E[hff; Li log hff; Li] 1 and ffm 0 ....

.... 1 and m 0 (ff) exists and is finite. Then the following are equivalent: i) P[W (ff) 0] q; ii) P[W (ff) 0] 1; iii) E[W (ff) 1; iv) E[hff; Li log hff; Li] 1 and ffm 0 (ff) m(ff) log m(ff) Remark. In fact, the hypotheses here are very slightly weaker than those of Biggins (1977), Lemma 5. Moreover, the proof to follow works without the assumption that m 0 (ff) be finite, except for the implication (ii) iv) where it needs the assumption that ffm 0 (ff) 6= Gamma1. Remark. The case of Biggins Theorem where L is constant, X i are independent and identically ....
