When viewed as a group, the isomorphisms reduce to well-known geometric transformations. We obtain new characterizations for linear, simple matrix, simple contextual and trace languages. Our results make it possible to transfer results concerning languages in one family into results concerning languages in another family. <\/jats:p>","DOI":"10.1142\/s0129054197000021","type":"journal-article","created":{"date-parts":[[2003,10,15]],"date-time":"2003-10-15T20:35:19Z","timestamp":1066250119000},"page":"1-14","source":"Crossref","is-referenced-by-count":1,"title":["Geometric Transformations of Language Families: The Power of Symmetry"],"prefix":"10.1142","volume":"08","author":[{"given":"Alexandru","family":"Mateescu","sequence":"first","affiliation":[{"name":"Turku Centre for Computer Science and Department of Mathematics, University of Turku, 20514 Turku, Finland"}]},{"given":"Grzegorz","family":"Rozenberg","sequence":"additional","affiliation":[{"name":"Leiden University, Department of Computer Science, P.
