测试Qexo在线发布文章

测试

Qexo是Hexo的后台管理程序，我将其托管在Vercel上，现在我可以在后台管理网站上在线编辑或发布博客文章，而不必在本地编译后发布。可惜无法发布到我的服务器上，这也比较危险。

数学公式测试

Let $Y$ be an arbitrary compactification of $Y$; let $\beta(X)$ be the Stone-Cech compactification. Show there is a continuous surjective closed map $g : \beta(X) \to Y$ that equals the identity on $X$.
[This exercise makes precise what we mean by saying that $\beta(X)$ is the “maximal” compactification of $X$. It shows that every compactification of $X$ is equivalent to a quotient space of $\beta(X)$.]
