I have a problem with typing some special mathematical expressions or symbols. They are

3:

and I need a refined form of enter image description here in which the \right> is typed better than it is.

    Each of them is straightforward to obtain with simple arrays or tikz-cd or other tools. However, I fear that if you expect somebody to convert all of these screen shots to LaTeX code, you may be waiting a long time. – Schrödinger's cat Oct 17 at 4:08
  • Dear @Schrödinger's cat, what is the tikz-cd ? I have never heard of it. – AYBRXQD Oct 17 at 4:24

    Please see tex.stackexchange.com/questions/tagged/tikz-cd to get an idea. – Schrödinger's cat Oct 17 at 5:40
  • The angle brackets are not generally available in sizes larger than you get in the picture. – egreg Oct 17 at 9:00

As for tikz-cd:

\documentclass{article}
\usepackage{amsfonts}
\usepackage{tikz-cd}
\begin{document}
\[\begin{tikzcd}[arrows={dash},column sep=0.2ex]
 & & \mathfrak{u}(6)\arrow[lld]\arrow[rrd]\arrow[d] & & \\
 \mathfrak{u}(5) \arrow[dr]& &\arrow[dl] \mathfrak{so}(6) & &
 \mathfrak{su}(3)\arrow[ddll] \\
 &  \mathfrak{so}(5)\arrow[dr]& & \phantom{\mathfrak{so}(5)} & \\
 & & \mathfrak{so}(3) \arrow[d]& & \\
 & & \mathfrak{so}(2) & & \\
\end{tikzcd}\quad\begin{tikzcd}[arrows={dash},column sep=0.2ex]
 & & A_5\arrow[lld]\arrow[rrd]\arrow[d] & & \\
 A_4 \arrow[dr]& &\arrow[dl] D_3 & &
 A_2\arrow[ddll] \\
 &  B_2\arrow[dr]& & \phantom{B_2} & \\
 & & B_2 \arrow[d]& & \\
 & & D_1 & & \\
\end{tikzcd}
\]
\end{document}

  • +1 especially for using fraktur for the algebras ;-) – campa Oct 17 at 9:23
  • @campa Thanks! I did not correct the missing \mathfrak{u}(1) factors, nor point out that D_1 is, at least, "unusual". – Schrödinger's cat Oct 17 at 9:25

A possible realization of the first one. There are surely smarter ways but it's enough for something written down before the first coffee...

\documentclass{article}

\usepackage{newtxtext,newtxmath}

\begin{document}

\[
\left|\,
\begin{array}{*{9}{@{}c}@{}}
u(6) & {}\supset{} & so(6) & {}\supset{} & so(5) & {}\supset{} & so(3) & {}\supset{} & so(2) \\
\downarrow && \downarrow && \downarrow && \downarrow && \downarrow \\
N && \sigma && \tau,\nu_\Delta && L && M_L
\end{array}
\,\right\rangle
\]

\end{document}
