The methods are quite elementary, and will be of interest for researchers in deformation theory, local singularities and Hilbert functions.\u003c\/p\u003e \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 1994-12-16\u003c\/p\u003e \u003cp\u003eFormat: Paperback\u003c\/p\u003e \u003cp\u003eISBN-13: 9783540587903\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/BFb0074026\u003c\/p\u003e \u003cp\u003eDimensions: 235cm x155cm\u003c\/p\u003e \u003cp\u003ePages: 182\u003c\/p\u003e ","brand":"Springer Berlin Heidelberg","offers":[{"title":"Default Title","offer_id":45369709428876,"sku":"9783540587903","price":35.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9783540587903.jpg?v=1772801213","url":"https:\/\/fh90cf-fv.myshopify.com\/products\/9783540587903","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
