DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MITLie/35/">
 Total positivity in symmetric spaces</a>\nby George Lusztig (MIT) as part 
 of MIT Lie groups seminar\n\nLecture held in 2-142.\n\nAbstract\nThe theor
 y of total positive matrices in GL_n(R) was initiated by Schoenberg (1930)
  and Gantmacher-Krein (1935) and extended to reductive groups in my 1994 p
 aper. It turns out that much of the theory makes sense also for symmetric 
 spaces although some new features arise.\n
