Resumen:
Let H be a Hilbert space and L(H) be the algebra of all bounded linear operators from H to H. Our goal in this article is to study the set $P.Lh$ of operators in $L(H)$ that can be factorized as the product of an orthogonal projection and a self-adjoint operator. We describe $P.Lh$ and present optimal factorizations, in different senses, for an operator in this set.
