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.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9781461429692\"\u003e\u003ch3\u003eAnalytic Hypoellipticity and the Courage to Localize High Powers of T\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9781461429692","offer_id":39416741232733,"sku":"9781461429692","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c9487fae-2665-402b-afc4-56037639e3cb.jpg?v=1781237710","url":"https:\/\/shop.autorenwelt.de\/en\/products\/nonelliptic-partial-differential-equations-analytic-hypoellipticity-and-the-courage-to-localize-high-powers-of-t-von-david-s-tartakoff","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
