Polarization structure of gravitational waves in extended relativity
Yaakov Friedman
We analyze the polarization structure of gravitational waves in the framework of Extended Relativity (ER), using the deviation tensor as the fundamental observable quantity. Starti…

Superposition Principle in Relativistic Gravity
Y. Friedman
We develop a framework for superposition in relativistic gravity within Extended Relativity (ER), a Lorentz-covariant theory formulated in flat spacetime. In this approach, gravita…

A unifying physically meaningful relativistic action
Y. Friedman
We introduce a relativistic action that provides a unified and physically meaningful description of particle dynamics in external fields. The proposed action is constructed to be L…
