Equigeodesics on flag manifolds
Nir Cohen, Lino Grama, Caio J. C. Negreiros
This paper provides a characterization of homogeneous curves on a geometric flag manifold which are geodesic with respect to any invariant metric. We call such curves homogeneous e…

The quaternionic determinat
Nir Cohen, Stefano De Leo
The determinant for complex matrices cannot be extended to quaternionic matrices. Instead, the Study determinant and the closely related -determinant are widely used. We show th…
