I have found myself now several pages into a maths paper for my university degree, and I am writing it in the less familiar AMSART document class. The document class is very neat and everything works and looks great, but I have a minor issue with the amount of white-space between the bold first-page title and the top of the page. This amount of spacing is way too much for this document as I am restricted to 11 pages and so I need to make efficient use of spacing. My (generalised) code is given below.

Ideally, I would like the bold title (first thing on the first page) to be 2cm away from the very top of the page, like the headers on every other page. I have tried playing around with \vspace, even tried using the titling package, but this doesn't work due to some form of package clash (apparently). I know that this document class is rather strict but I really want to carry on using it.

Any form of help or suggestions are very much appreciated.

The \vspace{-1cm} command inside \author is of no use. Just type \space*{-1.2cm}just before \maketitle.

Alternatively you might want to take a look at the titling package, which provides tools to customise the \maketitle command in a clean way.

Unrelated: the hyperref package should be loaded as the last one, with very few exceptions.

  • Leaving formatting instructions in the argument of \author is exactly what should be avoided.

  • @egreg: I know, but I didn't have time to check how titling interferes with amsart.

    When I put \space*{-1.2cm} right before \maketitle, it moves things up as desired, but it also bizarrely places the text "*{-1.2cm}" at the top of the page. Any idea what's happening? Are there other packages I should be using? Aug 26, 2018 at 23:34
  • Without a code, I don't see. However, note that if you use the titling package, you have a \droptitle length, which gives possibilities to fine-tune the vertical position of the title.

    Oh, did you intend to say \vspace*{-1.2cm}? That seems to work properly. Aug 29, 2018 at 2:45

another method for countering the space above the title is to nullify the \topskip applied above the title. this is used elsewhere, so the value isn't changed, but a reversing \vspace* is added after it:

\usepackage{etoolbox}
\makeatletter
\patchcmd{\@maketitle}{\global\topskip42\p@\relax}
  {\global\topskip42\p@\relax \vspace*{-38pt}}
  {}{}
\makeatother

it's easy to change this value if you decide you want something slightly different.

the code should be put in your preamble. i suggest at the very top, immediately following the \documentclass line.

I don't find the space is excessive. However, here's an easy way for adjusting the spacing, act where indicated after experimenting with the values.

I removed your hack for sharing the counter between equations and theorems and alike environments to a better one.

Remove the showframe option to geometry for the production version.
