我目前正在尝试向 FPSAC 发送一篇论文。到目前为止一切顺利，但我收到以下警告：
Overfull \vbox (3.26552pt too high) has occurred while \output is active
我知道它出现在哪里：它是标题。类别如下（我无法根据提交的要求进行更改）：

\abstract{Considering Schur positivity of differences of plethysms of homogeneous symmetric functions, we introduce a new relation on integer partitions. This relation is conjectured to be a partial order, with its restriction to one part partitions equivalent to the classical Foulkes conjecture. We establish some of the properties of this relation via the construction of explicit inclusion of modules whose characters correspond to the plethysms considered. We also prove some stability properties for the number of irreducible occurring in these modules as $n$ grows.}

有人知道我该怎么做才能在不改变课程的情况下摆脱这个问题吗？我对自定义类了解不够，无法确切理解会发生什么……
答案1
问题出在标题上，而不是标题上，这没问题。无需更改类，您可以扩大序言中的头部高度，警告就会消失。（无需加载 xcolor 包。它已包含在类中）。
该课程是为该活动量身定制的。也许你应该向组织者发送评论，因为同样的问题会影响其他同样细心的参与者。

这是使用的输出
\setlength{\headheight}{16pt}
并且没有它（如在原始文件中一样）并生成
Overfull \vbox (3.26552pt too high) has occurred while \output is active
如您所见，分页完全相同。
