Chapters focus on the problems of convergence and summability of spectral decompositions about the fundamental functions of elliptic operators of the second order. The author's work offers a novel method for estimation of the remainder term of a spectral function and its Riesz means without recourse to the traditional Carleman technique and Tauberian theorem apparatus.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Hardcover","offer_id":45284735189143,"sku":"9780306110375","price":3672.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9780306110375.webp?v=1769282070","url":"https:\/\/atlanticbooks.com\/products\/spectral-theory-of-differential-operators-self-adjoint-differential-operators-9780306110375","provider":"Atlantic Books","version":"1.0","type":"link"}
