Abstract
These pages summarize recent progress on the oscillation problem for semilinear elliptic partial differential equations of the form (1) in unbounded domains Ω in n-dimensional Euclidean space Rn. Our attention is restricted to the second order symmetric equation (1), and completeness is not attempted; the emphasis is on results obtained in the last five years.Keywords
