A perturbation solution of linear elliptic equation
The first boundary value problem for eΔu + a(x,y,e)ux + b(x,y,e)uy +c(x,y,e)u = d(x,y,e) for small e. This problem with coefficients independent of e was treated by Norman Levinson and appeared in Annals of Mathematics, Vol. 51, No. 2, March, 1950 [TRUNCATED].
