<正>We are concerned with the uniqueness of solutions of the Cauchy problemand a(s),b(s) are appropriately smooth.Since a(s) is allowed to have zero points, we
In a recent paper [ 1 ], Ye has demonstrated that the singular nonlinear elliptic equation △u =f(u1 | ↓△u|, |x|)/u^λ, x∈R^2,0 < λ < 1 has a positive entir
Higson have introduced the conception of “Higson's corona” (see [1]). For a given metricspace χ, it is a kind of compactification of χ related to the me
Consider I pairs of independent binomial variates X0i and X1i, with corresponding parameters P0i and P1i and sample sizes n0i and n1i for i = 1,…… , I. Let △
