RT Journal Article T1 A singular perturbation in a linear parabolic equation with terms concentrating on the boundary A1 Rodríguez Bernal, Aníbal AB In this paper we consider linear parabolic problems when some reaction and potential terms are concentrated in a neighborhood of a portion I" of the boundary. This neighborhood shrinks to I" as a parameter epsilon goes to zero. Then we derive the limit equation which has some new terms on I". We also analyze the regularity and convergence of the solutions.
