Yet another derivation of special relativity transformations without the second postulate
Josep Llosa

TL;DR
This paper derives the most general inertial frame transformations using basic assumptions, avoiding the need for the second postulate of special relativity, thus broadening the theoretical foundation of relativistic physics.
Contribution
It provides a derivation of special relativity transformations without relying on the constancy of the speed of light, offering a new perspective on foundational assumptions.
Findings
Derived transformations without the second postulate
Showed invariance under general assumptions
Revealed broader conditions for relativistic transformations
Abstract
The most general transformation connecting inertial frames is derived from rather general and simple assumptions, without the postulate of constancy of the speed of light in vacuo.
