Focusing on Fejér and Cesàro summability, as well as theta-summation, readers will become more familiar with a wide variety of summability methods. Within the theory of higher dimensional summability of Fourier series, the book also provides a much-needed simple proof of Lebesgue's theorem, filling a gap in the literature. Recent results and real-world applications are highlighted as well, making this a timely resource. The book is structured into four chapters, prioritizing clarity throughout. Chapter One covers basic results from the one-dimensional Fourier series, and offers a clear proof of the Lebesgue theorem. In Chapter Two, convergence and boundedness results for the lq-summability are presented. The restricted and unrestricted rectangular summability are provided in Chapter Three, as well as the sufficient and necessary condition for the norm convergence of the rectangular theta-means. Chapter Four then introduces six types of Lebesgue points for higher dimensional functions. Lebesgue Points and Summability of Higher Dimensional Fourier Series will appeal to researchers working in mathematical analysis, particularly those interested in Fourier and harmonic analysis. Researchers in applied fields will also find this useful. 001437418 650_0 $$aFourier series. 001437418 650_0 $$aSummability theory. 001437418 650_6 $$aSéries de Fourier. 001437418 650_6 $$aSommabilité. 001437418 655_0 $$aElectronic books. 001437418 77608 $$iPrint version: $$z3030746356$$z9783030746353$$w(OCoLC)1243349442 001437418 852__ $$bebk 001437418 85640 $$3Springer Nature$$uhttps://univsouthin.idm.oclc.org/login?url=https://link.springer.com/10.1007/978-3-030-74636-0$$zOnline Access$$91397441.1 001437418 909CO $$ooai:library.usi.edu:1437418$$pGLOBAL_SET 001437418 980__ $$aBIB 001437418 980__ $$aEBOOK 001437418 982__ $$aEbook 001437418 983__ $$aOnline 001437418 994__ $$a92$$bISE
