Some oscillation theorems for a class of quasilinear elliptic equations

  • Hiroyuki Usami


Oscillation criteria are obtained for quasilinear elliptic equations of the form (E)below. We are mainly interested in the case where the coefficient function oscillates near infinity. Generalized Riccati inequalities are employed to establish our results.
