An Extension of the L ATEX theorem environment ∗

Abstract

The macros described in this paper yield an extension of the L ATEX theorem mechanism. It is designed is to satisfy the different requirements of various journals. Thus, the layout of the “theorems ” can be manipulated by determining a “style”. This article describes not only the use, but also the definition, of the necessary macros. Preface to version 2.2 For L ATEX 2ε this package did not need any fundamental changes. I only modified the messages generated so that theorem layout styles will show up with the \listfiles command and cleaned the section on the New Font Selection Scheme since this is now included in L ATEX. Preface to version 2.1 This version is identical to 2.0g described in TUGboat 10#3 except for some internal defaults which are now set depending on the used font selection scheme. This was done to avoid unpleasant surprises if the new font selection scheme is in force. For further details see section 3 and [1]. 1
