κ-Minkowski Spacetimes and DSR Algebras: Fresh Look and Old Problems

Symmetry, Integrability and Geometry: Methods and Applications, 2010
Some classes of Deformed Special Relativity (DSR) theories are reconsidered within the Hopf algebraic formulation. For this purpose we shall explore a minimal framework of deformed Weyl-Heisenberg algebras provided by a smash product construction of DSR ...

Relational Observables in Gravity: a Review

Symmetry, Integrability and Geometry: Methods and Applications, 2012
We present an overview on relational observables in gravity mainly from a loop quantum gravity perspective. The gauge group of general relativity is the diffeomorphism group of the underlying manifold.

A relativistic approach to teaching electrodynamics: Deriving Maxwell's equations from first principles

Science Education Quarterly
This paper presents a novel methodology for teaching classical electrodynamics based on special relativity theory. Traditional approaches often rely heavily on empirical laws, potentially obscuring the fundamental unity of electromagnetic phenomena.

Building a conceptual profile for the conception of reference frame in physics and the epistemological obstacles to the learning of Special Theory of Relativity [PDF]

Investigações em Ensino de Ciências, 2010
In this work, we use de notion of Conceptual Profile as a theoretical tool to investigate the learning of the Special Theory of Relativity (STR) and the epistemological obstacles to its understanding.

A Field-Theoretic Gravitodynamic Framework Consistent with General Relativity

Reports in Advances of Physical Sciences
We present a covariant field-theoretical model of gravitation based on a structural analogy with classical electrodynamics. The theory employs a four-potential formulation and introduces dynamic gravitational fields, including a gravitomagnetic component

Quantum Gravity in 2+1 Dimensions: The Case of a Closed Universe

Living Reviews in Relativity, 2005
In three spacetime dimensions, general relativity drastically simplifies, becoming a "topological" theory with no propagating local degrees of freedom. Nevertheless, many of the difficult conceptual problems of quantizing gravity are still present.
