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.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Edizioni della Normale\u003c\/p\u003e \u003cp\u003ePublication Date: 1999-10-01\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9788876422898\u003c\/p\u003e \u003cp\u003eDOI: \u003c\/p\u003e \u003cp\u003eDimensions: 240cm x170cm\u003c\/p\u003e \u003cp\u003ePages: 108\u003c\/p\u003e ","brand":"Scuola Normale Superiore","offers":[{"title":"Default Title","offer_id":46266264420492,"sku":"9788876422898","price":13.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9788876422898.jpg?v=1770817697","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9788876422898","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
