%0 Journal Article %T A discrete anisotropic model for Scheibe aggregates %A O. Bang %A P. L. Christiansen %J Le Matematiche %D 1991 %I University of Catania %X A discrete anisotropic nonlinear model for the dynamics of Scheibe aggregates is investigated. The collapse of the collective excitations found by M bius and Kuhn is described as a shrinking ring wave, which is eventually absorbed by an acceptor molecule. An optimal acceptor loss is found. %U http://www.dmi.unict.it/ojs/index.php/lematematiche/article/view/597
