The geometry of Hermitian self-orthogonal codes
Journal of Geometry - Tập 113 - Trang 1-12 - 2021
We prove that if
$$n >k^2$$
then a k-dimensional linear code of length n over
$${\mathbb F}_{q^2}$$
has a truncation which is linearly equivalent to a Hermitian self-orthogonal linear code. In the......

Zur Struktur Geschlitzter Doppelräume
Journal of Geometry - Tập 5 - Trang 27-38 - 1974
Let (P,
$$\mathfrak{G}$$
,∥ℓ,∥r) be an incidence space with two parallelisms ∥ℓ and ∥r. (P,
$$\mathfrak{G}$$
,∥ℓ,∥r) is called double space [5], if for any two intersecting lines A and B and for any two points ......
Locally regular coloured graphs
Journal of Geometry - - 1992
In this work we introduce the concept of locally regular coloured graph as a generalization to any dimension of the concept of regularity for maps on surfaces of W. Threlfall. We prove that locally regular coloured graphs can be obtained from the classical spherical, euclidean and hyperbollic tessellations. Finally we describe locally regular coloured graphs on spherical 3-manifolds.
On invariant submanifolds of Kenmotsu manifolds
Journal of Geometry - Tập 106 - Trang 109-122 - 2014
The object of the present paper is to obtain a necessary condition for a three dimensional invariant submanifold of a Kenmotsu manifold to be totally geodesic. Besides this we study an invariant submanifold of Kenmotsu manifolds satisfying Q(α, R) = 0 and Q(S, α) = 0, where S, R are the Ricci tensor and curvature tensor respectively and α is the second fundamental form. Finally, we construct an e......
Harmonic sections of normal bundles for submanifolds and their stability
Journal of Geometry - Tập 83 - Trang 57-64 - 2005
We study harmonic sections of the normal bundles for submanifolds. Especially, the stability of certain harmonic sections of the normal bundles for compact submanifolds in the spheres are considered.
Geometrical properties of some Euler and circular cubics. Part 1
Journal of Geometry - Tập 66 - Trang 72-103 - 1999
This sequel to our earlier paper (1995) continues the investigation of the Euler cubic curves therein defined, with particular reference to perspectivities and associated conics. Study of the circular cubic in this pencil, the Neuberg cubic, brings with it some discussion of the properties of circular cubics in general.
