# How can I make my LaTeX paper look like this?

I've seen MANY papers created with LaTeX that have the following format:

In particular, I like the font sizes and the way that section titles are centered and in all caps. Does anyone know if there is a document class for this look? I'm sure there is something for it since I've seen so many papers that look exactly like this... Thanks!

Looks like `amsart`. – lhf Jun 12 '14 at 2:55
You can download the paper source from the arXiv. In this case they use `\documentclass[12pt, a4paper]{amsart}` – Lev Bishop Jun 12 '14 at 2:57
What are the margins typically used on papers created using this class? Just the default ones or something special? I particularly like them on the second paper I posted. – Jason Williams Jun 12 '14 at 5:19
the first example is almost certainly `amsart`, but the second one, if based on `amsart`, doesn't have the default dimensions or the default type style for the authors. `amsart` has a default `30pc` width; the second example appears wider. (changing the width on `amsart` is not completely trivial.) – barbara beeton Jun 12 '14 at 13:04

It's `amsart`, a standard document class from the American Mathematical Society used in its journals and widely elsewhere, e.g., in arXiv. It's part of AMS-LaTeX.
AMS-LaTeX has been split in two on ctan and in tex live; the two parts are `amscls` (the classes and `amsthm`) and `amsmath'. – barbara beeton Jun 12 '14 at 12:54
