An Extension of the L A T E X-Theorem Evironment
Wolfgang May, A. Schlechte, Marienburger Weg · 1999
ntheorem.sty is a package for handling theorem-like environments. Aditionally to several features for dening the layout of theorem-like environments which can be regarded to be standard requirements for a theorem-package, it provides solutions for two related problems: placement of endmarks and generation of lists of theorem-like environments. In contrast to former approaches, it solves the problem of setting endmarks of theorem-like environments (theorems, denitions, examples, and proofs) automatically at the right positions, even if the environment ends with a displaymath or (even nested) list environments, it also copes with the amsmath package. This is done in the same manner as the handling of labels by using the .aux le. It also introduces the generation of lists of theorem-like environments in the same manner as listoffigures. Additionally, more comfortable referencing is supported. After running L ATEX several times (depending on the complexity of references, in general, three runs are sucien t), the endmarks are set correctly, and theoremlists are generated. Since ntheorem.sty uses the standard L ATEX ewtheorem command, existing documents can be switched to ntheorem.sty without having to change the .tex le. Also, it is compatible with L ATEX les using theorem.sty writ
