Total positivity in symmetric spaces

Abstract: The theory 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 paper. It turns out that much of the theory makes sense also for symmetric spaces although some new features arise.
