將內聯數學推到下一行，無需手動換行（保持對齊）

Question

在我的定理中，您可以看到定理第一行的數學表達式的位置超出了邊距。我不想破壞表達式，如果我在它之前換行，那麼理由就會變得混亂。我希望所有文字左對齊和右對齊，除了段落的開頭和結尾。我該怎麼做？謝謝？

\usepackage[amsmath, thmmarks]{ntheorem}
\usepackage[left=1.5in,right=1.5in,top=0.75in,bottom=.75in,centering,includeheadfoot]{geometry}

\begin{mainthm}\label{thm:VecSpa}
    A maximal set of independent tangency classes $\{[\gamma'(\lambda_0)]_{(\sigma)}\}$ is a basis for a vector space $\mathcal{V}$, and a tangency class of curve derivatives $[\gamma'(\lambda_0)]$ is a vector $\bm V\in\mathcal{V}$.
\end{mainthm}

Answer 1

\\並\newline強制換行，留下一行短線。\linebreak強制中斷而不失去合理性，以便您可以使用

classes\linebreak $....

Answer 2

\sloppy您可以在 後立即插入指令\begin{mainthm}\label{thm:VecSpa}。正如下面的螢幕截圖所示，字間間距可能會變得相當草率，但可以保持合理性。
