DOI: 10.1002/mana.70026
Abstract: We study resonances for Jacobi operators on the half lattice with matrix‐valued coefficients and finitely supported perturbations. We describe a forbidden domain, the geometry of resonances and their asymptotics when the main coefficient of the… read more here.

DOI: 10.1007/s11082-018-1352-0
Abstract: We describe a GNU-OCTAVE implementation of the Jacobi–Davidson style QR method for the estimation of interior eigenvalues in photonic crystal structures. The photonic eigenproblem is reduced to a matrix eigenproblem using plane-wave expansion. We show… read more here.

DOI: 10.1007/s40072-019-00153-7
Abstract: We show that for a family of randomly kicked Hamiton-Jacobi equations on the torus, almost surely, the solution of an initial value problem converges exponentially fast to the unique stationary solution. Combined with the results… read more here.
