Hypersurfaces in a conformally flat space with curvature collineation [PDF]

International Journal of Mathematics and Mathematical Sciences, 1991
We classify the shape operators of Einstein and pseudo Einstein hypersurfaces in a conformally flat space with a symmetry called curvature collineation. We solve the fundamental problem of finding all possible forms of non-diagonalizable shape operators.

The geometry of GL(2,q) in translation planes of even order q2

International Journal of Mathematics and Mathematical Sciences, 1978
In this article we show the following: Let π be a translation plane of even order q2 that admits GL(2,q) as a collineation group. Then π is either Desarguesian, Hall or Ott-Schaeffer.

Translation planes of even order in which the dimension has only one odd factor

International Journal of Mathematics and Mathematical Sciences, 1980
Let G be an irreducible subgroup of the linear translation complement of a finite translation plane of order qd where q is a power of 2. GF(q) is in the kernel and d=2sr where r is an odd prime. A prime factor of |G| must divide (qd+1)∏i=1d(qi−1).

Elementary Abelian 2-subgroups in an Autotopism Group of a Semifield Projective Plane

Известия Иркутского государственного университета: Серия "Математика", 2020
Elementary Abelian 2-subgroups in an Autotopism Group of a Semifield Projective Plane} We investigate the hypotheses on a solvability of the full collineation group for non-Desarguesian semifield projective plane of a finite order (the question 11.76 in ...

Collineation groups of translation planes of small dimension

International Journal of Mathematics and Mathematical Sciences, 1981
A subgroup of the linear translation complement of a translation plane is geometrically irreducible if it has no invariant lines or subplanes. A similar definition can be given for “geometrically primitive”.

Timelike and spacelike Ricci collineation vectors in string fluid [PDF]

, 2003
We study the consequences of the existence of timelike and spacelike Ricci collineation vectors (RCVs) for string fluid in the context of general relativity.
