ISIM(2) gravitational gauge model via Soft Algebra formalism
Abstract
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 formalism. After presenting a closed form for sim(2) and its inhomogeneous extension, we proceed to develop a complete torsionless gravitational model, culminating in an invariant action.
