On Ranges of Lyapunov Transformations II †
Raphael Loewy · Linear and Multilinear Algebra · 1974
The Lyapunov transformation corresponding to the matrix is a linear transformation on the space of hermitian matrices of the form Given a positive stable , the Stein-Pfeffer Theorem characterizes those where B is similar to A and H is positive definite. Here several extensions of this theorem are proved
