• Sommario/riassunto: Building on the success of the two previous editions, Introduction to Hilbert Spaces with Applications, 3E, offers an overview of the basic ideas and results of Hilbert space theory and functional analysis. It acquaints students with the Lebesgue integral, and includes an enhanced presentation of results and proofs. Students and researchers will benefit from the wealth of revised examples in new, diverse applications as they apply to optimization, variational and control problems, and problems in approximation theory, nonlinear instability, and bifurcation. The text also includes a popular cha

• Sommario/riassunto: In The Eyes of the People entwickelt der Politikwissenschaftler Jeffrey Edward Green unter der Bezeichnung »Okulare Demokratie« eine grundlegend neue Theorie demokratischer Teilhabe. Dabei wird der Blick der Bürger_innen als Instrument demokratischer Kontrolle hervorgehoben, in dessen Fokus nicht Inhalte, sondern die öffentliche Performance von Spitzenpolitiker_innen steht. Der Band stellt diese Demokratietheorie vor und macht den Ansatz sowie die Diskussion um ihn erstmals für den deutschen Diskurskontext zugänglich. Die Beiträger_innen greifen dabei die Debatte um die Krise der repräsentativen Demokratie auf und untersuchen die Potenziale einer plebiszitären Zuschauerdemokratie.; Besprochen in: Zivilgesellschaft Info, 3 (2017)
