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.

Notes on Cooperstein Ovoids in Finite Geometries of Type 𝖤6,1
MathematicsA Cooperstein ovoid is a set of q8+q4+1 pairwise non-collinear points in the Lie incidence geometry E6,1(q). They were introduced by Cooperstein twenty-six years ago, motivated by the fact that possible non-existence of them would imply non-existence of ...

Collineation groups of the smallest Bol 3-nets
, 1994 Some associativity properties of a loop can be interpreted as certain closure configuration of the corresponding 3-net. If was known that the smallest non-associative loops with the so called left Bol property have order 8.In this paper we determine the ...

Translation planes of order $q2$ admitting collineation groups of order $q3u$ preserving a parabolic unital [PDF]
, 2006 The set of translation planes of order $q2$ that admit collineation groups of order $q3u$, where u is a prime p-primitive divisor of $q2-1$, consists of exactly the Desarguesian plane, assuming that the group does not contain a translation subgroup of ...

Linear collineation groups preserving an arc in a M\"{o}bius plane [PDF]
, 1999 The theory of $k$-arcs plays an important role in the study of Steiner triple systems, designs, and Benz planes (namely, Mö́bius, Laguerre and Minkowski planes).

Primitive collineation groups of ovals with a fixed point [PDF]
, 2003 We investigate collineation groups of a finite projective plane of odd order n fixing an oval and having two orbits on it, one of which is assumed to be primitive. The situation in which the group fixes a point off the oval is considered.

The Flag-Transitive Collineation Groups of the Finite Desarguesian Affine Planes
, 1964 Let π be the Desarguesian affine plane of order n = pr, for p a prime and r a positive integer. A collineation group G of π is defined to be flag-transitive on π if G is transitive on the set of incident point-line pairs, or flags, of π.

On Finite Collineation Groups of F5
, 1969 Our aim in this paper is to fill one gap left in (1) and to prove that if H is a finite collineation group of F5, the free plane generated by a finite open configuration of rank 9, then |H | ≦ 12.

The Collineation Group of the Veblen-Wedderburn Plane of Order Nine
, 1970 In this paper we prove that the order of the collineation group of the Veblen-Wedderburn plane of order nine is 311,040. This result was stated by Hall [3] in 1943 and proved by Pierce [9] in 1964.
