Sadržaj:
- <blockquote> <p>This work demonstrates that viable late-time interacting dark-sector solutions collapse onto a one-dimensional ridge due to fast–slow dynamical reduction near a scalar-field dominated fixed point.</p> <p> </p> <p>Across 76 numerically verified viable solutions, the interaction history exhibits near-universal shape (CV < 1% after alignment), with the peak amplitude linearly related to the effective amplitude parameter.</p> <p> </p> <p>The ridge structure is interpreted as the projection of an attracting invariant manifold, providing a dynamical explanation for the narrow viable band observed in parameter space.</p> <p> </p> <p>A covariant embedding via disformal coupling and a schematic derivation of the interaction four-vector are provided to establish microphysical consistency.</p> </blockquote>
