定理编号与定理之间如何留空格？

Question

不确定您的意思，但是\swapnumbers如果您定义并使用指定最后一个参数的自定义定理样式，则您不应该使用\newtheoremstyle。

这是您前言的编辑版本，相当混乱：首先加载软件包，这样可以避免重复和不兼容。请注意，hyperref必须是最后一个（除了您的软件包中不存在的几个例外）。

我添加了关于软件包的评论。特别是，不抑制连字，但使用babel以获得西班牙语的正确连字。

我还更改了\newtheoremstyle声明，因为\parshape原来的声明没有任何意义。请注意，使用此新代码，您无需为定理标签或正文指定字体。

注意：您thm根据进行定义thmx，但不要定义后者。

\begin{theo}[Fundamental de la programación lineal]
Si un PPL tiene soluciones óptimas. alguna de ellas se alcanza en uno 
de los vértices del conjunto convexo $S$ de soluciones factible. Si, 
además, se alcanza solución óptima en más de un vértice de $S$, también 
son soluciones óptimas las combinaciones lineales convexas de dichos vértices.
