On unitary collineation groups

open access: yesJournal of Algebra, 1972
If II is a finite projective plane of order q2 over the field K = GF(q2), then 17 admits a polarity 6 which is induced on I7 by a nondegenerate hermitian form on the underlying vector space. The subgroup of the little projective group PSL,(q2) which centralizes 6 is the projective special unitary group PSU,(q). The purpose of this paper is to show that

Matter and Ricci Collineations [PDF]

open access: yes, 2013
The infinitesimal transformations that leave invariant a two-covariant symmetric tensor are studied. The interest of these symmetry transformations lays in the fact that this class of tensors includes the energy-momentum and Ricci tensors. We find that in most cases the class of infinitesimal generators of these transformations is a finite dimensional ...

Special Recurrent Transformation in an NPR-Finsler Space

open access: yesCubo, 2012
In this paper, an infinitesimal transformation , where the vector vi is recurrent has been considered in an NPR- Finsler space. Such transformation is being called special recurrent transformation if the recurrence vector of the NPR- Finsler space is Lie
