Geometry of unitary orbits of pinching operators

Eduardo Chiumiento, María E. Di Iorio y Lucero

Let I be a symmetrically-normed ideal of the space of bounded operators acting on a Hilbert space H. Let $p_{i}_{1}^{w}$ $(1 \leq w \leq \infty)$ be a family of mutually orthogonal pro…

Stiefel and Grassmann manifolds in Quantum Chemistry

Eduardo Chiumiento, Michael Melgaard

We establish geometric properties of Stiefel and Grassmann manifolds which arise in relation to Slater type variational spaces in many-particle Hartree-Fock theory and beyond. In p…
