The pseudoarc is a co-existentially closed continuum

通过对P.Bankston的一个问题的讨论，我们证明了伪弧是一个共存闭连续统。我们还表明，$C(X)$，为$X$一个非退化连续，永远不能有量词消除，回答了一个问题的第一和第三命名的作者和法拉和Kirchberg。
英文摘要：
Answering a question of P. Bankston, we show that the pseudoarc is a co-existentially closed continuum. We also show that $C(X)$, for $X$ a nondegenerate continuum, can never have quantifier elimination, answering a question of the the first and third named authors and Farah and Kirchberg.
