Oscillation Criteria for a Class of Perturbed Schrödinger Equations
Oscillation Criteria for a Class of Perturbed Schrödinger Equations
We are concerned with the oscillatory behavior of the second order elliptic equation 1 where Δ is the Laplace operator in n -dimensional Euclidean space R n , E is an exterior domain in R n , and c : E × R → R and f:E → R are …
