%0 Journal Article %T On a parabolic operator of dissipative systems %A Monica De Angelis %J Physics %D 2013 %I arXiv %X A parabolic integro differential operator operator L suitable to describe many phenomena in various physical fields,is considered. By means of equivalence between L and the third order equation which describe the evolution inside an exponentially shaped Josephson junction (ESJJ), an asymptotic analysis for (ESJJ) is achieved, evaluating explicitly boundary contributions related to the Dirichlet problem. %U http://arxiv.org/abs/1307.1887v1
