Pada tahun 1922, Harald Bohr dan Johannes Mollerup membuat karakterisasi fungsi gamma Euler yang luar biasa menggunakan sifat log-konveksitasnya. Satu dekade kemudian, Emil Artin menyelidiki hasil ini dan menggunakannya untuk memperoleh sifat dasar fungsi gamma menggunakan metode dasar kalkulus. Teorema Bohr-Mollerup kemudian diadopsi oleh Nicolas Bourbaki sebagai titik awal untuk pemaparannya …
In 1922, Harald Bohr and Johannes Mollerup established a remarkable characterization of the Euler gamma function using its log-convexity property. A decade later, Emil Artin investigated this result and used it to derive the basic properties of the gamma function using elementary methods of the calculus. Bohr-Mollerup's theorem was then adopted by Nicolas Bourbaki as the starting point for his …
Aimed toward researchers and graduate students familiar with elements of functional analysis, linear algebra, and general topology; this book contains a general study of modulars, modular spaces, and metric modular spaces. Modulars may be thought of as generalized velocity fields and serve two important purposes: generate metric spaces in a unified manner and provide a weaker convergence, the m…
