Talk:Signature (universal algebra)

Merge with signature (mathematical logic)
The definition of a signature in this article is incorrect (actually encodes an entire structure instead of just describing an interface), and has been so for well over a year. This is also a case of duplication, since signatures in model theory are only slightly more general. Therefore I will replace this article by a forward to signature (mathematical logic). --Hans Adler 03:04, 16 November 2007 (UTC)
