Algebra", "categories": [ "math.AC", "math.AG" ], "abstract": "In this paper we study the star operations on a pullback of integral domains. In particular, we characterize the star operations of a domain arising from a pullback of ``a general type'' by introducing new techniques for ``projecting'' and ``lifting'' star operations under surjective homomorphisms of integral domains. We study the transfer in a pullback (or with respect to a surjective homomorphism) of some relevant classes or distinguished properties of star operations such as $v-, t-, w-, b-, d-,$ finite type, e.a.b., stable, and spectral operations. We apply part of the theory developed here to give a complete positive answer to a problem posed by D. F. Anderson in 1992 concerning the star operations on the ``$D+M$'' constructions.", "revisions": [ { "version": "v1", "updated": "2003-11-05T15:11:39.000Z" } ], "analyses": { "subjects": [ "13A15", "13G05", "13C99" ], "keywords": [ "star operations", "integral domains", "surjective homomorphism", "complete positive answer", "spectral operations" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2003math.....11060F" } } }
