摘要
给出可拓集经典域与可拓域、可拓域与非域的边界关联函数值K(?)(u)=0,-1的新定义,从而得到了新的可拓集结构。
This paper gives a new mathematical definition for extendible set's classical domain, extendible domain and boundary related function value between extendible domain and non-domain. As a consequence, it gets a new structure of extendible set.
