Embedded eigenvalues for perturbed periodic Jacobi operators using a geometric approach

Edmund Judge, Sergey Naboko, Ian Wood

We consider the problem of embedding eigenvalues into the essential spectrum of periodic Jacobi operators, using an oscillating, decreasing potential. To do this we employ a geomet…

Essential spectrum for Maxwell's equations

Giovanni S. Alberti, Malcolm Brown, Marco Marletta +1

We study the essential spectrum of operator pencils associated with anisotropic Maxwell equations, with permittivity , permeability and conductivity , on finite…
