gravitational gauge model via Soft Algebra formalism
J. M. B. Matzenbacher, J. M. Hoff da Silva
This work presents a comprehensive account of a gravitational model based on the gauging of the Lorentz subgroup parameters through the so-called soft algebra fo…
Notes on obstructions in the hyperbolic Clifford algebra bundle structure
J. M. Hoff da Silva, E. Notte-Cuello
Starting from a general analysis of obstruction classes, we develop the investigation of obstructions associated with the bundle structure of the hyperbolic Clifford algebra. By ta…
Breaking the permutation character of diffeomorphisms on spinor structures
J. M. Hoff da Silva
We investigate the impact of diffeomorphisms where more than one nonequivalent spinor structure is built upon a given base manifold endowed with nontrivial topology. We call attent…
Foundational aspects of spinor structures and exotic spinors
J. M. Hoff da Silva
Spinors are mathematical objects susceptible to the spacetime characteristics upon which they are defined. Not all spacetimes admit spinor structure; when it does, it may have more…
