Description: I envision the course proceeding in four stages: I. Some necessary background in Complex Analysis. II. Web1 Introduction As a projective variety, the moduli space Mg of Riemann surfaces of genus g is swept out by algebraic curves. Only rarely, however, are these curves isometrically embedded for the Teichmu¨ller metric. jhkh investments llcWebWe explore possible interpretation of those findings in the context of the cinematic view of cognition, in particular cortical phase transitions. In addition to traditional Fourier-based correlational analysis of cortical signals, we introduce Hilbert analysis, which allows to monitor rapid phase synchronization-desynchronization transitions. jhk forecasts twitter

"WebThis volume contains six sets of notes for lectures on the foundations of geometry held by Hilbert in the period 1891-1902. It also reprints the first edition of Hilbert’s celebrated Grundlagen der Geometrie of 1899, together with the important additions which appeared first in the French translation of 1900.
