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 \u003ch3\u003eDetails\u003c\/h3\u003e \u003cp\u003ePublished by: Springer\u003c\/p\u003e \u003cp\u003ePublication Date: 1995-08-31\u003c\/p\u003e \u003cp\u003eFormat: Hardcover\u003c\/p\u003e \u003cp\u003eISBN-13: 9780306110375\u003c\/p\u003e \u003cp\u003eDOI: 10.1007\/978-1-4615-1755-9\u003c\/p\u003e \u003cp\u003eDimensions: 254cm x178cm\u003c\/p\u003e \u003cp\u003ePages: 390\u003c\/p\u003e ","brand":"Springer US","offers":[{"title":"Default Title","offer_id":46546135711884,"sku":"9780306110375","price":49.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/9545\/1788\/files\/9780306110375.jpg?v=1775789726","url":"https:\/\/lateknightbooks.com\/products\/9780306110375","provider":"Late Knight Books and Services, LLC","version":"1.0","type":"link"}
