Wave propagation in periodic lattices with defects of smaller dimension

Published 20 May 2013 in math-ph and math.MP | (1305.4568v1)

Abstract: The procedure of evaluating of the spectrum for discrete periodic operators perturbed by operators of smaller dimensions is obtained. This result allows to obtain propagative, guided, localised spectra for different kind of physical operators on graphs with defects.
