Spectral data and solvent theory for regular matrix polynomials
Nir Cohen, Edgar Pereira
This paper contains a re-evaluation of the spectral approach and factorizability for regular matrix polynomials. In addition, solvent theory is extended from the monic and comonic…
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…
Quaternionic commutations
N. Cohen, S. De Leo, G. Ducati
Given n quaternions we investigate the extent of non-commutativity of their multiple products, commutators and exponential products.
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…
