We first recap some of the main ideas of algebraic number theory, using these to develop the Artin reciprocity law and the Takagi existence theorem both in terms of ideals and ideles. Finally, we use the Hilbert class field in order to study the well known problem of which prime numbers can be represented in the form x 2 + ny 2 for integers x, y and positive integer n.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/3/64/096/929/3640969294_b.jpg", "price_data" : { "retail_price" : "19.90", "online_price" : "19.90", "our_price" : "19.90", "club_price" : "19.90", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
