La Fórmula Fundamental de la Geometría no Euclidiana

, 2023
El presente artículo presenta dos formas distintas de obtener la llamada fórmula de la geometría no euclidiana. La primera asume la idea de Taurinus en cuanto que las fórmulas de la geometría hiperbólica se obtienen de la trigonometría de una esfera con ...

Ways of linking geometry and algebra, the case of Geogebra

, 2007
This paper discusses ways of enhancing the teaching of mathematics through enabling learners to gain stronger links between geometry and algebra. The vehicle for this is consideration of the affordances of GeoGebra, a form of freely-available open-source

Spin 1 Particle in the Magnetic Monopole Potential for Minkowski and Lobachevsky Spaces: Nonrelativistic Approximation

, 2015
The spin 1 particle is treated in the presence of the Dirac magnetic monopole in the Minkowski and Lobachevsky spaces. Separating the variables in the frame of the matrix 10-component Duffin–Kemer–Petiau approach and making a nonrelativistic approximation ...

Quasi-plane waves for a particle with spin 1/2 on the background of Lobachevsky geometry: simulating of a special medium

, 2012
In the paper complete systems of exact solutions for Dirac and Weyl equations in the Lobachevsky space are constructed on the base of the method of separation of the variables in quasi-cartesian coordinates. An extended helicity operator is introduced.
