Extension to dynamical pseudo-complex spacetimes

Extend the constitutive framework beyond stationary pseudo-complex spacetimes to dynamical solutions, gravitational waves, and cosmological models.

Background

The construction in the paper is based primarily on static and rotating stationary solutions, with the static solution determining the trace-sector constitutive law and the rotating solution indicating the relevance of additional transverse structure. The authors explicitly identify the extension of this framework to genuinely dynamical settings as unresolved, including gravitational-wave and cosmological applications.
