Derives an explicit reconstruction formula for the contrast in the 2D acoustic inverse Born scattering problem by decoupling the linear system into independent triangular subsystems using Zernike decompositions solved via forward substitution.
Defines differentiable weak distance on SE(3) for surface measures via Sobolev norms and shows local optimization with trust-region methods and NUFFT gradients.
