Abstract This article examines some of the theoretical issues that exercised Sergei Eisenstein during years 1920–1924 when he worked in Russian Proletarian Cultural-Educational Organization (Proletkult), which Aleksandr Bogdanov was one founders. We ask how far influenced by Marxism general and ideas particular, explain his exit from Proletkult terms unacceptability theory practice theatre film...

Abstract. Kac–Moody groups G over R have been conjectured to occur as symmetry groups of supergravities in dimensions less than 3, and their integer forms G(Z) are conjecturally U– duality groups. Mathematical descriptions of G(Z), due to Tits, are functorial and not amenable to computation or applications. We construct Kac–Moody groups over R and Z using an analog of Chevalley’s constructions ...

Previous research has shown how various technologies became the market standard. This chapter presents some refined models and applies them to the case of compressed audio formats. The authors analyze the rise of MP3 as the market standard and identify several key factors that contributed to its success. First, a process of formal standardization reduced the number of competing compressed audio...

The p-adic interpolation properties of Fourier coefficients of elliptic Eisenstein series are by now classical. These properties can be considered as the starting point and as an important tool in the theory of p-adic L-functions and p-adic families of modular forms. In the case of Siegel modular forms there are two types of Eisenstein series. A Siegel Eisenstein measure which comes from the Si...
