The present book proposes a novel approach to the topic based on techniques from noncommutative geometry, especially the spectral action functional as a gravity model. The book discusses applications to early universe models and slow-roll inflation models, to the problem of cosmic topology, to non-isotropic cosmologies like mixmaster universes and Bianchi IX gravitational instantons, and to multifractal structures in cosmology.\u003c\/p\u003e\u003cp\u003eRelations between noncommutative and algebro-geometric methods in cosmology is also discussed, including the occurrence of motives, periods, and modular forms in spectral models of gravity.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"World Scientific Publishing Company, Incorporated","offers":[{"title":"Default Title","offer_id":47185218011376,"sku":"9789813202863","price":38.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9789813202863_p0.jpg?v=1763690326","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9789813202863","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
