Collapsing domain walls generically form cuspidal edge and vertex singularities captured by Nambu-Goto and eikonal approximations and reproduced in field theory simulations.
Hyperbolic DBI remains caustic-free for generic waves on planar domain walls in 2D flat space and under realistic deformations; only hyperbolicity loss produces cusp caustics.
Bayesian multiband analysis shows LISA and Taiji reconstruct PTA-compatible domain wall parameters in the strong-signal regime, with joint PTA priors reducing 10D degeneracies.
Collapsing Z_N domain walls trap baryons into dense baryoids, yielding a dark matter-baryon energy density ratio of approximately (N-1):1 after the QCD phase transition.
Generalization of scalar-fermion Yukawa systems in constant-EOS cosmologies identifies scaling regime with constant energy density ratio from approximate scale invariance and asymptotic regime recovering bare mass.
