C-infinity Compact-Support Wormholes with Exact Schwarzschild Exterior in Trace-Coupled Gravity

We study static, spherically symmetric traversable wormholes in trace-coupled gravity with action density f(R,T) = R + lambda T^2. The spacetime is built from C-infinity deformations of Schwarzschild that vanish identically outside a finite core, so the exterior is exactly Schwarzschild and no thin shell or junction su...
