Title: Control sets and total positivity
Author: Ayala, V
Kliemann, W
San Martin, LAB
Abstract: The objective of this article is to bring together two different mathematical subjects, namely totally positive matrices and control sets. It describes the control sets of the totally positive matrices and the sign-regular matrices in flag manifolds. In particular, the classical result by Gantmacher and Krein, follows from Theorem 9.7. One expects that with this description some theorems proved by combinatorial techniques have a geometric or dynamic interpretation.
