... X.ThenV and W disconnect Y if and only if Y = V ∪ W, V ∩W = ∅, V = ∅, W = ∅ , and any triangle which is contained in Y is either contained in V or contained in W .WesaythatY is disconnected if and ... Define ψ : A → X 1,k and τ : B → X 1,k by ψ(F, G)=(F, (G\{k +1}) ∪{k} )and (F, G)= (F, G\{k +1}). Then ψ and τ are injective and take triangles to triangles, so one may choose Z...

... to find the joint PDF p C ˙ C (z, ˙z) of C(t) and its time derivative ˙ C(t). The joint PDF p C ˙ C (z, ˙z) can be found by using the joint PDF p Ξ 2 ˙ Ξ 2 (z, ˙z) given in (5) and by employing ... = F C (r) N C (r) (18) where F C (r) and N C (r) are given by (4) and (8), respectively. 4 Asymptotic analysis In this section, we will study the PDF, CDF, mean, and variance of the...

Lemma 3.2 Let E be a closed interval on the real line and T : E → E be a con- tinuous and nondecreasing mapping such that F(T ) is nonempty and bounded ... u 1 > u 1 and Tx 1 > x 1 . By using (1.9), (1.11) and the same argument as in Case 1, we can show that x n ≥ u n for all n ≥ 1. We note that x 1 < L and by using (1.11)...
