Le. Payne et al., BOUNDS AND DECAY RESULTS FOR SOME 2ND-ORDER SEMILINEAR ELLIPTIC PROBLEMS, Mathematical methods in the applied sciences, 21(17), 1998, pp. 1571-1591
The asymptotic behaviour of solutions of certain semilinear elliptic D
irichlet boundary value problems defined on a semi-infinite cylinder i
s investigated by means of energy arguments and maximum principles. Va
rious hypotheses are made on the form of the semilinear term, and in s
ome cases it is found that the rate of decay of solutions is faster th
an the optimal decay rate for harmonic functions. (C) 1998 B. G. Teubn
