Description: |
Complex interpolation (Nevanlinna-Pick or
Schur-Caratheodory type) can be explained from several
points of view, and I will offer yet another one:
comparative stability. Here, given two (complex or
real) matrices A,B, the question is to verify whether
every Lyapunov factor for A is a Lyapunov factor for B
(we say that H is a Lyapunov factor for X if X^TH+HX
is positive semi-definite). The Pick matrix comes out
here as the right hand side HA+AH for a very special matrix. Area(s):
