Equidimensional and Unmixed Ideals of Veronese Type

摘要

This article was motivated by a problem left by Herzog and Hibi, namely, to classify all unmixed polymatroidal ideals. In the particular case of polymatroidal ideals corresponding to discrete polymatroids of Veronese type, i.e., ideals of Veronese type, we give a complete description of the associated prime ideals, and then we show that such an ideal is unmixed if and only if it is Cohen-Macaulay. We also give for this type of ideals equivalent characterizations for being equidimensional.View full textDownload full textKey WordsDiscrete polymatroids, Equidimensional ideals, Ideals of Veronese type, Squarefree strongly stable ideals, Unmixed ideals2000 Mathematics Subject Classification13C05, 13C14Related var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00927870802107595
