论文摘要
我们介绍了连续的新类; $ d^{**} $ - $ continua $。 Wilder Continua和$ d^{*} $ - continua的类别严格包含在$ d^{**} $ - continua的类中。此外,$ d $ -continua的类大于$ d^{**} $ - continua的类。使用$ d^{**} $ - continua,我们对问题给出负面答案。此外,我们证明自己是$ d $,是$ d^*$,而为$ d^{**} $是惠特尼属性。
We introduce the new class of continua; $D^{**}$-$continua$. The classes of Wilder continua and $D^{*}$-continua are strictly contained in the class of $D^{**}$-continua. Also, the class of $D$-continua is bigger than the class of $D^{**}$-continua. Using $D^{**}$-continua, we give the negative answer to a Question. Furthermore, we prove that being Wilder, being $D$, being $D^*$ and being $D^{**}$ are Whitney properties.
