Evolutes of plane curves and null curves in Minkowski $3$-space

, 2016
We use the isotropic projection of Laguerre geometry in order to establish a correspondence between plane curves and null curves in the Minkowski $3$-space.

Age-based Predictive Model of the Pediatric Ribcage

International Journal of Automotive Engineering, 2014
Ribcage geometry of 327 boys and girls (aged 1-18) was extracted from CT scans, consisting of three dimensional curves fit through the centroidal path of 6306 individual ribs.

Plane Symmetric Domain Wall in Lyra Geometry

, 2002
In this paper general solutions are found for domain walls in Lyra geometry in the plane symmetric spacetime metric given by Taub. Expressions for the energy density and pressure of domain walls are derived in both cases of uniform and time varying ...

Problem in Plane Geometry [PDF]

Proceedings of the Edinburgh Mathematical Society, 1907
In a plane, a point O and a straight line OH drawn through O are given. OH is the bisector of an unknown angle YOX, which it is required to determine by the following conditions: A point I, given by position in the plane of the figure, is connected with the straight line OH by the given angle IOH =θ, and by the distance OI=c, from the point I to the

UNIFORM SPANNING FORESTS OF PLANAR GRAPHS

Forum of Mathematics, Sigma, 2019
We prove that the free uniform spanning forest of any bounded degree proper plane graph is connected almost surely, answering a question of Benjamini, Lyons, Peres and Schramm.

Ideals on the Quantum Plane’s Jet Space

Mathematics, 2020
The goal of this paper is to introduce some rings that play the role of the jet spaces of the quantum plane and unlike the quantum plane itself possess interesting nontrivial prime ideals.

THE FULFILLED EUCLIDEAN PLANE [PDF]

, 2009
The fulfilled euclidean plane is the real projective plane, completed with the infinite point of its infinite line denoted new incidence structure. This is a structure with neighbouring elements, in which the unicity of the line through two distinct ...

An Axiomatic Basis for Plane Geometry [PDF]

Transactions of the American Mathematical Society, 1933
1. The axioms. The fourth appendix of Hilbert's Grundlagen der Geometriet is devoted to the foundation of plane geometry on three axioms pertaining to transformations of the plane into itself. The object of the present paper is to attain the same end by quicker and simpler means.
