Matrix systems, algebras, and open maps
Original language description
Every state on the algebra Mn of complex n x n matrices restricts to a state on any matrix system. Whereas the restriction to a matrix system is generally not open, we prove that the restriction to every *-subalgebra of Mn is open. This simplifies topology problems in matrix theory and quantum information theory.
