Equigeodesic vectors for homogeneous Riemannian submersions
Neiton Pereira da Silva, Brian Grajales, Lino Grama
We study -equigeodesic vectors associated with homogeneous fibrations, namely vectors that are geodesic with respect to every homogeneous metric making the projection a Riemann…

Cohomogeneity one Einstein metrics on complex projective spaces
Anderson L. A. de Araujo, Brian Grajales, Lino Grama
We study Einstein metrics on complex projective spaces that are invariant under cohomogeneity one actions of compact connected Lie groups, under the assumption that the singular or…

Characterizing Optimal-speed unitary time evolution of pure and quasi-pure quantum states
John A. Mora RodrÃguez, Brian Grajales, Marcelo Terra Cunha +1
We present a characterization of the Hamiltonians that generate optimal-speed unitary time evolution and the associated dynamical trajectory, where the initial states are either pu…
