私は脚注のグローバル システム (番号付き) を 1 つだけ用意しようとしていますが、分割可能な tcolorboxes に問題があるようです。私が読んだ回答の多くは、単一のグローバル脚注システムという私の単純な要件には高度すぎるようです。
私の前置きは
\documentclass[a4paper,10pt,titlepage]{article}
\usepackage[utf8]{inputenc}
\newcommand{\myparagraph}[1]{\paragraph{#1}\mbox{}\\}
\usepackage[a4paper,margin=3.5cm]{geometry} %Sets the page geometry
\usepackage{url}
\usepackage{dirtytalk}
\usepackage{graphicx} % Package for \includegraphics
\usepackage{wrapfig} % Figure wrapping
\usepackage[T1]{fontenc} % Output font encoding for international characters
\setlength{\parskip}{1em} % Set space when paragraphs are used
\usepackage{amssymb}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{mathtools}
\usepackage{hyperref}
\usepackage{mathrsfs}
\usepackage{mdframed}
\usepackage[breakable]{tcolorbox}
\usepackage[justification=centering]{caption}
\usepackage{soul}
% Note that we enforce things so that everything is numbered off of theorems
\theoremstyle{definition} % to avoid italicizing theorems
\newmdtheoremenv{theo}{Theorem}
\newtheorem{thm}{Theorem}[section] % reset theorem numbering for each chapter
\newtheorem{defn}[thm]{Definition} % definition numbers are dependent on theorem numbers
\newtheorem{rmk}[thm]{Remark}
\newtheorem{exmp}[thm]{Example} % same for example numbers
\newtheorem{crlry}[thm]{Corollary}
\newtheorem{lemma}[thm]{Lemma}
\newtheorem{problem}{Problem}[section]
%% HOW TO KEEP FOOTNOTES GLOBAL
\usepackage{footnote}
\usepackage{etoolbox}
\BeforeBeginEnvironment{tcolorbox}{\savenotes}
\AfterEndEnvironment{tcolorbox}{\spewnotes}
\usepackage{blindtext}
\usepackage{geometry}
%\usepackage{showframe} %This line can be used to clearly show the new margins
\newgeometry{vmargin={25mm}, hmargin={22mm,22mm}}
% Lets you use \blankpage to make a blank page
\newcommand{\blankpage}{
\newpage
\thispagestyle{empty}
\mbox{}
\newpage
}
私の脚注の例を次に示します。
\begin{tcolorbox}[breakable]
\begin{defn}[Equivalence class]
Given an equivalence relation $\equiv$ defined on a set $S$, we define the equivalence class corresponding to any $a \in S$ as the set\footnote{If the equivalence relation in question is understood from context we'll sometimes just write $[a]$.}
$$[a]_\equiv = \{ b \in S | a \equiv B \}$$
\end{defn}
\end{tcolorbox}
私の問題の例は、以下の図に示されています (それぞれ脚注「a」で始まる 2 つの tcolorboxes に注意してください)。ただし、tcolorboxes の外部で実行した操作は問題なく、グローバルで正しく増分されます。
ご協力いただければ幸いです。ありがとうございます!

これは\BeforeBeginEnvironment
と の両方を組み合わせたものであることに注意してください\renewenvironment
。これは、オプションの引数の前または後にコマンドを実行することに関係しています。
