{"product_id":"9780486154497","title":"Plane Waves and Spherical Means Applied to Partial Differential Equations","description":"This collection of results on partial differential equations employs certain elementary identities for plane and spherical integrals of an arbitrary function, showing how a variety of results on fairly general differential equations follow from those identities. Explores the decomposition of arbitrary functions into functions of the type of plane waves; Radon transformation; more. 1955 edition.","brand":"Dover Publications","offers":[{"title":"Default Title","offer_id":47112136294640,"sku":"9780486154497","price":10.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780486154497_p0.jpg?v=1763708407","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780486154497","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
