Related to a previous post, now pardon me to go to a specific example,

here is my output

enter image description here

and my Minimum Working Environment

\documentclass[onecolumn,amsmath,amssymb,nofootinbib,superscriptaddress,floatfix]{revtex4}
\begin{document}



$$
\begin{CD}
1+1 @>>> 2+1 @>>> 3+1 @>>> \dots @>>> d+1 \dots\\
12 @<<< 123 @<<< 1234 @<<< \dots @<<< 123(d+1)\\
@| @| @|\\
 @>>> xy  @<<< xyz @<<<
\end{CD}
$$


\end{document}

Question: what I wish is that the similar diagram as above: but having the following conditions:

(i) all the leftarrow @>>> removed, but keeps the same spacing as before.

(ii) all the down equal line removed @| removed, but the same (or smilier) spacing

(iii) connecting xyz to 12 from the right to the left arrow (<---)

(iii) may be challenging, so it is fine to neglect this (iii), and your reply on (i)(ii) still count as an answer.

Thank you, any comment is welcome and helpful! :)

  • You could have waited for my answer on the previous post: I did promise to write an answer! Does my answer in that post help you with this one? I think all you need to is replace by @. and that is it! Edit: I don't think you can do slant arrows in AMSCD package! I am writing a quick tikz-cd answer to this question! – kan May 27 '14 at 17:51

Since this question is tagged , here is a tikz-cd answer: 

\documentclass{amsart}
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}
1+1 & 2+1       & 3+1        & \cdots       & d + 1 \\
12  & 123 \ar{l}& 1234 \ar{l}& \cdots \ar{l}& 123 \dots (d+1) \ar{l}\\
    & xy \ar{ul}& xyz  \ar{l}& \ar{l}
\end{tikzcd}
\end{document}

The output:

Update: Here is an answer with xypic as you asked in the comments: 

\documentclass{amsart}
\usepackage[all]{xy}
\begin{document}
$\xymatrix{
1+1 & 2+1       & 3+1        & \dots        & d + 1 \\
12  & 123 \ar[l]& 1234 \ar[l]& \cdots \ar[l]& 123 \dots (d+1) \ar[l]\\
    & xy \ar[ul]& xyz  \ar[l]& \ar[l]
}$
\end{document}

The Output:

  • @ Kan, thanks, it is pretty clear! +1. – wonderich May 27 '14 at 18:24
  • but excuse me what if I also need an arrow from xyz to 12. Not just xy to 12? – wonderich May 27 '14 at 18:27
  • also, I cannot compile it successfully, via \documentclass[onecolumn,amsmath,amssymb,nofootinbib,superscriptaddress,floatfix,amsart]{revtex4} – wonderich May 27 '14 at 18:28
  • I could not compile it even using your set-up:

    \documentclass{amsart} \usepackage{tikz-cd}

  • @Idear, what is the error message: something like missing package? It would help if you tell me the version of TeXLive or MikTeX that you may be using? – kan May 27 '14 at 18:36
  • Could one use \xymatrix{} instead, will that also work? If you know \xymatrix{}, that can count as a separate answer. :) – wonderich May 27 '14 at 18:44
  • OK, let me try... regarding your other question about arrows, the general rule is, if you want an arrow, the direction is specified by u, d, r, l with their obvious meanings. And, you can use a combination of them like I did: so, llu would be an answer to your question; left, left, up is the instruction you would tell xyz if (s)he wanted to 12. Any other valid instruction works too :-) – kan May 27 '14 at 18:59
  • @Idear See my updated answer! – kan May 27 '14 at 19:47
