我试图在 Beamer 中将引文写为脚注。但它不适合框架。我该如何写？请给我一些建议。
答案1
使用\footnotemark/\footnotetext方法，您可以实现以下目标：

Godsil\footnotemark[1] posed the problem of characterizing the bipartite graphs with a unique perfect matching which possesses an inverse. Akbari and Kirkland\footnotemark[2] characterized the bipartite, unicyclic graphs with a unique perfect matching possessing an inverse. Among all such invertible bipartite, unicyclic graphs with
