不完整的 TQFT 圖和多餘的空間

Question

我正在使用 Andrew Stacey 的套件來繪製座標（看到這個問題），我有兩個問題。

首先，如何才能實現如下圖的繪圖？準確地說，我將如何創建一個胖的共邊，其中一些傳入和傳出缺少邊界塊，即未繪製但由垂直點暗示？

第二，如何去除反面褲子下方的多餘空間？它影響括號

\documentclass{article}
\usepackage{tikz}
\usepackage{tqft}
\begin{document}
\[
S_M\left(\quad
\begin{tikzpicture}[tqft/flow=east]
    \node[draw, tqft, reverse pair of pants, boundary lower style={draw,dashed}] (A) {};
    \node[tqft boundary circle,draw] at (A.outgoing boundary 1) {};
\end{tikzpicture}
\quad\right)=\bullet
\]
\end{document}

Answer 1

足夠接近...

\documentclass{article}
\usepackage{tikz}
    \usetikzlibrary{tqft}
\begin{document}
\[
    p\left\{\vphantom{\vrule height80pt}\right.
    \begin{tikzpicture}[baseline=57pt,ultra thick,red]
        \pic[
            tqft,rotate=90,
            cobordism height=70pt,boundary separation=30pt,
            cobordism edge/.style={draw},
            incoming boundary 2/.style={dotted},
            incoming upper boundary component 2/.style={dotted},
            incoming lower boundary component 2/.style={dotted},
            incoming boundary 3/.style={dotted},
            between outgoing 2 and 3/.style={dotted},
            outgoing upper boundary component 2/.style={dotted},
            outgoing lower boundary component 2/.style={dotted},
            between outgoing 1 and 2/.style={dotted},
            incoming boundary components=5,
            outgoing boundary components=4,offset=.5,
            every upper boundary component/.style={draw},
            every lower boundary component/.style={draw,thin},
            genus=3,
            hole 1/.style={rotate=-90,shift={(0pt,130pt)}},
            hole 2/.style={rotate=-90,shift={(-20pt,100pt)}},
            hole 3/.style={rotate=-90,shift={(-60pt,60pt)}},]{};
    \end{tikzpicture}
    \left.\vphantom{\vrule height60pt}\right\}q
