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","brand":"Edizioni Della Normale","offers":[{"title":"Paperback","offer_id":47813633704087,"sku":"9788876422898","price":1563.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9788876422898.webp?v=1778337321","url":"https:\/\/atlanticbooks.com\/products\/de-concini-procesi-models-of-arrangements-and-symmetric-group-actions-9788876422898","provider":"Atlantic Books","version":"1.0","type":"link"}
