I understand how to use the theorem environment in LaTex and would like to know if there is a similar environment for postulates or how I can make an environment for postulates on my own.

1 Answer 1



\newtheorem{post}{Postulate}[chapter] (or [section])

in the preamble should be enough. Now you can use packages, such as amsthm or ntheorem to customise the layout of this new environment.

  • Thanks that works! Is there any way to get rid of the period after the number so that it just says Postulate 1 not Postulate 1.?

  • It depends on the package you use. I don't know very well amsthm, but with ntheorem, you must add theoremseparator{} if you don't want the full stop, or, say theoremseparator{ — } if you want an emdash (old style typography!) before declaring the environment.
