Abstract
espanolUn espacio topologico conexo Z es unicoherente si para cualesquiera A y B cerrados y conexos de Z, tales que Z = A ∪ B, se tiene que A ∩ B es conexa. Sea Z un espacio unicoherente: decimos que z ∈ Z agujera a Z si Z − {z} no es unicoherente. Un problema de reciente estudio es: dado un espacio topologico unicoherente H(Z), obtenido de un espacio topologico Z, ?cuales elementos A ∈ H(Z) lo agujerean? Este trabajo consiste en dar una resena de los resultados que hasta la fecha se conocen de este problema. EnglishA connected topological space Z is unicoherent provided that if Z = A ∪ B, where A and B are closed connected subsets of Z, then A ∩ B is connected. Let Z be a unicoherent space: we say that z ∈ Z makes a hole in Z if Z − {z} is not unicoherent. A problem of recent study is: given a topological space unicoherent H(Z), obtained from a topological space Z, which elements A ∈ H(Z) makes a hole? This work consists in giving a review of the results known to date of this problem.
连通拓扑空间Z是一相干的,如果对于Z的任意闭连通A和B,使Z = A∪B, A∩B是连通的。设Z是一个单相干空间:如果Z−{Z}不是单相干的,我们说Z∈Z与Z收敛。最近研究的一个问题是:给定一个由拓扑空间Z得到的一相干拓扑空间H(Z),哪些元素A∈H(Z)使它穿孔?这项工作是对迄今为止已知的这一问题的结果进行审查。连接拓扑空间Z是一致的,如果Z = A∪B,其中A和B是Z的封闭连接子集,那么A∩B是连接的。如果Z−{Z}不是单相干的,我们说Z∈Z在Z中形成一个洞。A problem of最近study is:给予topological space unicoherent H (Z),获得from A topological space Z which elements A∈H (Z)曾A hole ?= =地理= =根据美国人口普查,这个县的面积为。
