Separation and the existence theorem for second order nonlinear differential equation
Sufficient conditions for the invertibility and separability in $L_2(-\infty, +\infty)$ of the degenerate second order differential operator with complex-valued coefficients are obtained, and its applications to the spectral and approximate problems are demonstrated. Using a separability theorem, wh...
