time-delays

Bridging infinite-dimensional delay dynamics with fully GPU-accelerated finite-dimensional Koopman learning and provable error bounds for nonlinear delay-differential equations.

Temporal-Spatial Coupling in Gravitational Lensing: A Reinterpretation of Dark Matter Observations — Unstretched-space (3+1) ADM temporal refraction n(x)=1−2Φ_N/c²−β_A u_grav(x) on the zero-parameter two-branch action (k=16.03) reproduces Bullet Cluster convergence, SN Refsdal delay, and CMB lensing from baryons alone (c_GW=c_γ).
