Wintner-Type Oscillation Criteria of Semilinear Elliptic Inequalities

Abstract:
Wintner-type oscillation criteria of semilinear elliptic inequalities are obtained by using partial Riccati technique. The results here improve the oscillation criteria due to E. S. Noussair and C.A. Swanson [Canad. J. Math. (4)32 (1980), 908-923].

Keywords:
Oscillation, semilinear elliptic inequalities, second order, partial Riccati technique.
