I encounter some non-rendered latex in Definition 1.7 (sections) and Example 1.8 (trivial bundle).
Anyone else seeing this?

[Edit:] In Definition 1.14. sub-para "1": Typo? $dx^j$ in 2nd line should be $dx^i$ ?

Thanks. I fixed the indexing in Def. 1.14 now. I am not sure yet what is causing the two rendering issues. Will investigate...

Some diagrams which work ok contain:

\downarrow\substack{fb}

But both the faulty ones have: \downarrow^\substack{fb}

### Urs Schreiber

Thanks again. Yes, that's what triggers the problem. I have removed the "substack", and now it displays.

But an issue remains. The use of "substack" here is a hack anyway. It replaces what in my source is "mathrlap" or "mathllap", neither of which seem to be supported here. If anyone has a suggestion, please let me know.

It's offtopic a bit, because it's about technical things, but I'd suggest Greg should also admit collections of pdf's as Insights. Then it would be much easier to write Insights of such typographically challenging texts simply in LaTeX. The greatest obstacle writing Insights articles for me are these technical problems!

I know what you mean. On the other hand, with the script that some kind soul has written for me (who prefers to remain anonymous), 99% of the technical problems have now gone away (for conversion from Instiki to Wordpress that is, but something analogous could be done for conversion from LaTeX to Wordress.) I am confident that the last remaining little issues as above will be sorted out.

Found the solution! Turns out that the functionality of "mathrlap" and "mathllap" is supported here after all, but it needs to be called just as "rlap" and "llap".

Now everything works! (Or so it seems, please let me know if you spot further issues.)

Thanks for sharing this very interesting guide which you clearly took very seriously!

I actually think pdf-notes would be more comfortable to read (and more printer-friendly as well) though, especially on complex subjects like this.

### vanhees71

Still I prefer pdf's, particularly since I'm still preferring to print out manuscripts like this on paper. I'm a digital immigrant!

### Urs Schreiber

There is two different things you could be asking for here:
2. A reformatting in standard LaTeX style compiled to a pdf.
I'll provide the former when the series is finished. For the latter we would need somebody offering to write a conversion tool that would convert my source code to LaTeX.

### vanhees71

As long as the pdf is as readable as the web site and formatted in a way that it can be printed out nicely, I don't care with which tool it is created. Thanks anyway for all this work. I have to struggle to keep up reading and have negative available time at the moment :-(.

I tried to print some articles from your sequence using the browser's print facility (from chrome), and the result was very poor....

This makes it almost unreadable as there happen to be lots of links!

To be readable, each link should be replaced in the print version by a reference such as [3], and at the end of the article the reference numbers should be listed together with their link:
[3] http://xxxx.yy....

17. Nov 26, 2017

### Greg Bernhardt

Right, that is what I meant. There are some things I can try. Be back later to report.

18. Nov 26, 2017

### A. Neumaier

maybe you can make a button that generates a print version. In this case it would be useful to have a choice whether one wants to have all links simply suppressed, or listed in the way suggested above.

19. Nov 26, 2017

### Greg Bernhardt

Working on that now. First try looked good but now the latex doesn't render.

20. Nov 26, 2017

### A. Neumaier

Also, the pdf for the above Insight article has the leading table truncated.
Please place the print/pdf button at the top!

### Greg Bernhardt

PDF conversion won't work because it won't render the latex. I'll have to find a friendly print option.

22. Nov 27, 2017

### vanhees71

This brings up again my older suggestion to allow also to reach in Insight articles as pdf. Then the author can choose his or her preferred way of writing (LaTeX or even, horribile dictu, Word & Co) and provide a well readable and printable pdf. In the best of all worlds one should have both the pdf and the html version.

I think a way to provide the latter, using LaTeX should be the following: One types LaTeX and at the end translates via query replace to the format (I still don't know what it is, mathjax, WordPress, or something else?) of the Insights editor. The only quibble is that one has to provide also a list of private macro definitions used in the LaTeX. So it's perhaps a bit of cumbersome work to get the final Insights html version to look right.

### eys_physics

I fully agree with the suggestion by vanhees71. It would be very nice if at least some of the Insight articles could be read as pdf, at least the ones containing many equations.

24. Nov 27, 2017

### Greg Bernhardt

This is not easily possible as the latex is rendered by the web browser

25. Nov 27, 2017

### Urs Schreiber

At the very least, I know how to produce a readable single-file pdf from my source, formatted as web-display, but readable. I'll provide that when the series is finished.

But I am also in contact with people who think about looking into proper LaTeX conversion of my source. With a little luck, this will work out.
