UNIF is the main international meeting on unification. Unification is concerned with the problem of identifying given terms, either syntactically or modulo a given logical theory. Syntactic unification is the basic operation of most automated reasoning systems, and unification modulo theories can be used, for instance, to build in special equational theories into theorem provers.
The aim of UNIF'07, as that of the previous meetings, is to to bring together people interested in unification, present recent (even unfinished) work, and discuss new ideas and trends in unification and related fields. This includes scientific presentations, but also descriptions of applications and softwares using unification as a strong component. In 2007, UNIF is organized as part of the 2007 Federated Conference on Rewriting, Deduction, and Programming (RDP 2007).

This workshop is the twentyfirst in the series: UNIF'87 (Val D'Ajol, France), UNIF'88 (Val D'Ajol, France), UNIF'89 (Lambrecht, Germany), UNIF'90 (Leeds, England), UNIF'91 (Barbizon, France), UNIF'92 (Dagstuhl, Germany), UNIF'93 (Boston, USA), UNIF'94 (Val D'Ajol, France), UNIF'95 (Sitges, Spain), UNIF'96 (Herrsching, Germany), UNIF'97 (Orléans, France), UNIF'98 (Rome, Italy), UNIF'99 (Frankfurt, Germany), UNIF'00 (Pittsburgh, USA), UNIF'01 (Siena, Italy), UNIF'02 (Copenhagen, Denmark), UNIF'03 (Valencia, Spain), UNIF'04 (Cork, Ireland), UNIF'05 (Nara, Japan), UNIF'06 (Seattle, WA, USA).
