Asymptotics of the Solutions of the Sturm--Liouville Equation with Singular Coefficients

A. A. Shkalikov, V. E. Vladykina

We obtain asymptotic representations as $\lambda \to \infty$ in the upper and lower half-planes for the solutions of the Sturm--Liouville equation $$ -y"+p(x)y'+q(x)y= λ^2 ρ(x)y, \qquad x…
