{"product_id":"9781491059838","title":"Free Algebra with Countable Basis (Russian Edition)","description":"In this book I treat the structure of D-module which has countable basis. If we do not care for topology of D-module, then we consider Hamel basis. If norm is defined in D-module, then we consider Schauder basis. In case of Schauder basis, we consider vectors whose expansion in the basis converges normally.","brand":"CreateSpace Publishing","offers":[{"title":"Default Title","offer_id":48528821551345,"sku":"9781491059838","price":27.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/5433\/7265\/files\/9781491059838_p0.jpg?v=1786274424","url":"https:\/\/shop.barnesandnoble.com\/products\/9781491059838","provider":"Barnes \u0026 Noble","version":"1.0","type":"link"}
