introduction
double Bruhat cells
Bruhat order
Weyl group action
The decomposition of G into strata G^{u,v} is 'good with respect to total positivity.
example
SL_{3}(\mathbb{C})
u=v=w_0
u= s_1s_2s_1, \(\bar{i}\)
v= s_1s_2s_1, \(i\)
Take a shuffle \(\bar{2} 1 \bar{3}32\bar{1}\bar{2}1\bar{1}\).
Choose a sign for a minor.
