ABSTRACT

Some oscillation criteria for the second order semilinear elliptic dierential equation
$\sum^N_{i,j=1} D_i[a_{ij}(x)D_j y] + p(x)f(y) =0, \quad x \in \Omega(r_0), \quad (\text{E})$
are established. Particularly, Hille's theorem [Trans. Amer. Math. Soc. 64, 234-252(1948) ] is extended to (E).
