{"product_id":"david-s-s-tartakoff-nonelliptic-partial-differential-equations-9781461429692","title":"Nonelliptic Partial Differential Equations","description":"This book provides a very readable description of a technique, developed by the author years ago but as current as ever, for proving that solutions to certain (non-elliptic) partial differential equations only have real analytic solutions when the data are real analytic (locally). The technique is completely elementary but relies on a construction, a kind of a non-commutative power series, to localize the analysis of high powers of derivatives in the so-called bad direction. It is hoped that this work will permit a far greater audience of researchers to come to a deep understanding of this technique and its power and flexibility.","brand":"Springer","offers":[{"title":"Default Title","offer_id":53639389053270,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9781461429692_1_e027c8c7-563f-49a4-b66e-10eeb9e3531f.jpg?v=1778686976","url":"https:\/\/www.momoxbooks.com\/products\/david-s-s-tartakoff-nonelliptic-partial-differential-equations-9781461429692","provider":"momoxbooks","version":"1.0","type":"link"}
