C. Bandle et M. Marcus, ASYMPTOTIC-BEHAVIOR OF SOLUTIONS AND THEIR DERIVATIVES, FOR SEMILINEAR ELLIPTIC PROBLEMS WITH BLOWUP ON THE BOUNDARY, Annales de l Institut Henri Poincare. Analyse non lineaire, 12(2), 1995, pp. 155-171
By means of comparison functions the asymptotic behaviour of solutions
of semilinear elliptic equations which blow up at the boundary is est
ablished, The results depend only on the principal part of the second
order operator and can be expressed in a simple way in terms of the as
sociated Riemannian metric. In order to discuss the asymptotic behavio
ur of the derivatives a blowup technique together with a scaling argum
ent is used.
