Neumann cut-offs and essential self-adjointness on complete Riemannian manifolds with boundary
Davide Bianchi, Batu Güneysu, Alberto G. Setti
We generalize some fundamental results for noncompact Riemannian manfolds without boundary, that only require completeness and no curvature assumptions, to manifolds with boundary:…

Improved impedance inversion by the iterated graph Laplacian
Davide Bianchi, Florian Bossmann, Wenlong Wang +1
We introduce a data-adaptive inversion method that integrates classical or deep learning-based approaches with iterative graph Laplacian regularization, specifically targeting acou…
