我目前正在嘗試向 FPSAC 發送一篇論文。到目前為止一切順利，但我有以下警告：
Overfull \vbox (3.26552pt too high) has occurred while \output is active
我知道它出現在哪裡：那就是標題。該類別如下（我不能根據提交的要求進行更改）：

\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.}

有人知道我可以做些什麼來擺脫這個而不改變班級嗎？我對自訂類別了解不夠，無法準確理解會發生什麼事...
答案1
問題來自標題，而不是您的標題，這很好。在不改變類別的情況下，您可以擴大序言中的頭部高度，警告就會消失。 （不需要載入 xcolor 包。它已經包含在類別中）。
該課程是為該活動量身定制的。也許您應該向組織者發送評論，因為相同的問題會影響其他同樣細心的參與者。

這是使用的輸出

這沒有它（如在你的原始文件中）並產生

如您所見，分頁完全相同。
