Topologically induced deformations of differential forms

J. M. Hoff da Silva, J. M. B. Matzenbacher, R. da Rocha

Motivated by deformations of spin structures and their geometric implications, we study a deformed exterior derivative, which is a third-order nilpotent operator. This higher-order…

$ISIM (2)$ 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 $ISIM (2)$ Lorentz subgroup parameters through the so-called soft algebra fo…

From Lorentz to $S I M (2)$ : contraction, four-dimensional algebraic relations and projective representations

J. E. Rodrigues, J. M. B. Matzenbacher, G. M. Caires da Rocha +1

We present a comprehensive study on $S I M (2)$ and $I S I M (2)$ groups, their representations and algebraic aspects. These groups, together with $H O M (2)$ , arise as the symmetry groups o…
