Manifold Data Imputation
David Levin
We consider the problem of reconstructing missing data on a smooth manifold from incomplete and nonuniform samples. While classical methods for manifold approximation typically ass…

Understanding and Resolving Singularities in 3D Dirichlet Boundary Problems
David Levin
We introduce a two-phase approximation method designed to resolve singularities in three-dimensional harmonic Dirichlet problems. The approach utilizes the classical Green's functi…
