{ "item_title" : "Advances in Operator Theory and Approximation", "item_author" : [" Bidu Bhusan Jena", "Hemen Dutta", "Susanta Kumar Paikray "], "item_description" : "This book provides a rigorous examination of modern operator theory focusing on the construction and convergence of linear positive operators in generalized function spaces. In addition, the book explores how to create mathematical shortcuts that accurately represent complex, real-world data using simpler, more manageable formulas. By integrating advanced summability methods-such as A-statistical and deferred weighted convergence, the book provides refined techniques for function approximation. From Fourier signal processing to black-box optimization, these chapters contribute to bridging the gap between abstract functional analysis and its applications. Readers will gain a better understanding of modern linear positive operators and advanced summability methods that extend beyond the limitations of classical approximation theory. A versatile toolset for analyzing convergence within complex, generalized function spaces is provided and equips readers to deal with new problems in signal processing, black-box optimization, and modeling.In addition, this book: Extends classical approximation theory into complex, generalized function spaces and weighted environmentsIncludes statistical, deferred weighted, and Euler summability for approximation problems where traditional methods failAnalyzes a wide spectrum of linear positive operators including Bernstein, Stancu-Polya, and Kantorovich types ", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/3/03/240/166/3032401666_b.jpg", "price_data" : { "retail_price" : "44.99", "online_price" : "44.99", "our_price" : "44.99", "club_price" : "44.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
