Collineation groups of octonionic and split-octonionic planes [PDF]
, 2023 We present a Veronese formulation of the octonionic and split-octonionic projective and hyperbolic planes. This formulation of the incidence planes highlights the relationship between the Veronese vectors and the rank-1 elements of the Albert algebras ...

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.

Collineation groups of translation planes admitting hyperbolic Buekenhout or parabolic Buekenhout-Metz unitals [PDF]
, 2006 Publicación ISIIt is shown that for every semifield spread in PG(3, q) and for every parabolic Buekenhout-Metz unital, there is a collineation group of the associated translation plane that acts transitively and regularly on the affine points of the ...

Journal of Mathematics, Volume 2026, Issue 1, 2026.This article explores the necessary and sufficient conditions for a vector field on the cotangent bundle of a Riemannian manifold to qualify as an m− modified conformal vector field or a Ricci bi‐conformal vector field. The analysis employs an adapted frame and concerns the Riemannian extension metric.

Multistable Soft Robots Assembled from Bistable Auxetic Building Blocks
Advanced Intelligent Systems, Volume 7, Issue 4, April 2025.Bistable and multistable structures offer solutions for enhancing shape retention and load capacity in soft robots. This study presents a multistable soft robot design using bistable auxetic building blocks. Illustrated through a manipulator with 216 discrete stable states and a tube‐crawling robot, the design demonstrates significant versatility and ...

On collineation groups of translation planes of order q4
International Journal of Mathematics and Mathematical Sciences, 1986 Let P be an affine translation plane of order q4 admitting a nonsolvable group G in its translation complement. If G fixes more than q+1 slopes, the structure of G is determined.

Ovoids of PG(3,q) stabilized by a central collineation [PDF]
, 2003 In this paper we give a short proof that an ovoid of PG(3,q) is stabilized by a non-trivial central collineation of PG(3,q) if and only if it is an elliptic quadric. © 2003 Elsevier Science Ltd.

On Quasi‐Hermitian Varieties in Even Characteristic and Related Orthogonal Arrays
Journal of Combinatorial Designs, Volume 33, Issue 3, Page 109-122, March 2025.ABSTRACT In this article, we study the BM quasi‐Hermitian varieties, laying in the three‐dimensional Desarguesian projective space of even order. After a brief investigation of their combinatorial properties, we first show that all of these varieties are projectively equivalent, exhibiting a behavior which is strikingly different from what happens in ...
