Consider a linear system of the form d/dt x(t) = Ax. Next suppose there exists a positive definite solution to the matrix inequality:
A^TP + PA < 0
where M<0 means M is negative definite. Then prove that all
eigenvalues of A have negative real part.
Dear student,
This was a question of dynamical system, i have tried to solve it. Hope its helpful for you. Have written it stepwise.
