The Schur-Horn theorem for operators with finite spectrum
Marcin Bownik, John Jasper
We characterize the set of diagonals of the unitary orbit of a self-adjoint operator with a finite spectrum. Our result extends the Schur-Horn theorem from a finite dimensional set…

Constructive proof of the Carpenter's Theorem
Marcin Bownik, John Jasper
We give a constructive proof of Carpenter's Theorem due to Kadison. Unlike the original proof our approach also yields the real case of this theorem.

Diagonals of self-adjoint operators with finite spectrum
Marcin Bownik, John Jasper
Given a finite set we characterize the diagonals of self-adjoint operators with spectrum . Our result extends the Schur-Horn theorem from a finite dimensional set…
