Heat kernel coupling for multiple graph analysis
Michael M. Bronstein, Klaus Glashoff
In this paper, we introduce heat kernel coupling (HKC) as a method of constructing multimodal spectral geometry on weighted graphs of different size without vertex-wise bijective c…
Making Laplacians commute
Michael M. Bronstein, Klaus Glashoff, Terry A. Loring
In this paper, we construct multimodal spectral geometry by finding a pair of closest commuting operators (CCO) to a given pair of Laplacians. The CCOs are jointly diagonalizable a…
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…
