In particular we study their integer cohomology rings, which are torsion free Z-modules of which we find Z-bases. When the considered arrangement is the braid hyperplane arrangement, this leads to the study of the integer cohomology rings of the moduli spaces of n-pointed curves of genus 0 and of their Mumford-Deligne compactifications. We deal with the action of the symmetric group on the cohomology rings: we give explicit formulas for the associated generalized Poincaré series, and provide recursive formulas for the characters.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Giovanni Gaiffi\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 8876422897\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9788876422898\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Edizioni Della Normale\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 10\/01\/1999\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 108\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.56lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.46h x 6.66w x 0.34d","brand":"Giovanni Gaiffi","offers":[{"title":"Paperback","offer_id":48446517117183,"sku":"9788876422898","price":14.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_64903f9b-18e2-480b-ac21-a70dc1ba1816.jpg?v=1777225164","url":"https:\/\/www.whiterainbookhouse.com\/products\/de-concini-procesi-models-of-arrangements-giovanni-gaiffi-9788876422898","provider":"WR Book House","version":"1.0","type":"link"}
