A contractive version of a Schur-Horn theorem in II1 factors

We prove a contractive version of the Schur-Horn theorem for submajorization in II<sub>1</sub> factors that complements some previous results on the Schur-Horn theorem within this context. We obtain a reformulation of a conjecture of Arveson and Kadison regarding a strong version of the...

Sumario:We prove a contractive version of the Schur-Horn theorem for submajorization in II<sub>1</sub> factors that complements some previous results on the Schur-Horn theorem within this context. We obtain a reformulation of a conjecture of Arveson and Kadison regarding a strong version of the Schur-Horn theorem in II<sub>1</sub> factors in terms of submajorization and contractive orbits of positive operators.
