We describe sequences of zeros of functions f 0 analytic in the half-plane
and satisfying the condition
where : [0; +) (0; +) is an increasing function such that the function ln (r) is convex with respect to ln r on [1; +). 相似文献

Brugesser and Mani proved that the boundary-complex of a convex polytope can be shelled. This result lead to McMullen's proof of the Upper-bound-conjecture. We show that the shellability of complexes has a close connection to the theory of stellar operations. Several results on special shelling procedures and on non-shellable complexes are obtained. 相似文献

Regularization of Nonlinear Ill-Posed Variational Inequalities and Convergence Rates 总被引:12,自引:0,他引:12
Let H be a Hilbert space and K be a nonempty closed convex subset of H. For f H, we consider the (ill-posed) problem of finding u K for which 0 for all v K, where A : H H is a monotone (not necessarily linear) operator. We study the approximation of the solutions of the variational inequality by using the following perturbed variational inequality: for f H, f – f , find u, K for which 0 for all v K, where , , and are positive parameters, and K, a perturbation of the set K, is a nonempty closed convex set in H. We establish convergence and a rate O(1 / 3) of convergence of the solutions of the regularized variational inequalities to a solution of the original variational inequality using the Mosco approximation of closed convex sets, where A is a weakly differentiable inverse-strongly-monotone operator. 相似文献

If X is a real Banach space, then the inequality x defines so-called hyperbolic cone in E=X. We develop a relevant version of Perron-Frobenius-Krein-Rutman theory. 相似文献

The paper is concerned with Range-Domain Implications MvCvK, where M is a given operator and C,K denote given sets. Sufficient conditions are derived by a very general continuity principle. Various special cases are considered such as inverse-positivity, MvMwvw, and a generalization H(,[,])MvH(,[,]) v, where Mu=H(u,u) and [,] denotes an order interval. These results are applied to differential operators related to boundary or initial value problems. The goal is to furnish a simple uniform approach, to explain its application, and to provide a kind of survey on what problems have been treated in this way. 相似文献

It is well known that for certain sequences {tn}n the usual Lp norm ·p in the Paley-Wiener space PW
p
is equivalent to the discrete norm fp,{tn}:=(
n=–
|f(tn)|p)1/p for 1 p = < and f,{tn}:=sup
n|f(tn| for p=). We estimate fp from above by Cfp,
n
and give an explicit value for C depending only on p, , and characteristic parameters of the sequence {tn}n. This includes an explicit lower frame bound in a famous theorem of Duffin and Schaeffer. 相似文献
