Nonisometric Surface Registration via Conformal Laplace-Beltrami Basis Pursuit
Stefan C. Schonsheck, Michael M. Bronstein, Rongjie Lai
Surface registration is one of the most fundamental problems in geometry processing. Many approaches have been developed to tackle this problem in cases where the surfaces are near…
Asymptotic metrics on the space of matrices under the commutation relation
Klaus Glashoff, Michael M. Bronstein
We show that the norm of the commutator defines "almost a metric" on the quotient space of commuting matrices, in the sense that it is a semi-metric satisfying the triangle inequal…
Almost-commuting matrices are almost jointly diagonalizable
Klaus Glashoff, Michael M. Bronstein
We study the relation between approximate joint diagonalization of self-adjoint matrices and the norm of their commutator, and show that almost commuting self-adjoint matrices are…
