关于d.c.函数和凸函数的扩张

On extensions of d.c. functions and convex functions

Libor Vesely, Ludek Zajicek

摘要:

我们表明,我们最近的结果组合的直流功能(和映射)意味着积极的结果直流功能(和映射)的扩展。回答两个自然相关的问题的例子。关于连续凸函数从赋范线性空间的闭子空间的可拓性的两个定理补充了J.Borwein,V.Montesinos和J. Vanderwerff最近的结果。

英文摘要:

We show how our recent results on compositions of d.c. functions (and mappings) imply positive results on extensions of d.c. functions (and mappings). Examples answering two natural relevant questions are presented. Two further theorems, concerning extendability of continuous convex functions from a closed subspace of a normed linear space, complement recent results of J.Borwein, V.Montesinos and J.Vanderwerff.
