{ "item_title" : "Introduction to Supersymmetry and Supergravity (Revised and Extended 2nd Edition)", "item_author" : [" Peter West "], "item_description" : "The publication of the first edition of Introduction to Supersymmetry and Supergravity was a remarkable success. This second edition contains a substantial amount of new material especially on two-dimensional supersymmetry algebras, their irreducible representations as well as rigid and local (i.e. supergravity) theories of 2-dimensional supersymmetry both in x-space and superspace. These theories include the actions for the superstring and the heterotic string. In addition, a chapter is devoted to a discussion on superconformal algebras in two dimensions and contains an account of super operator product expansion.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/81/020/098/9810200986_b.jpg", "price_data" : { "retail_price" : "103.00", "online_price" : "103.00", "our_price" : "103.00", "club_price" : "103.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
