Spectral asymptotics for solutions of $2\times 2$ system of ordinary differential equations of the first order

A. P. Kosarev, A. A. Shkalikov

The aim of the paper is to find representation for solutions of $2\times 2$ system of ordinary differential equations $$ \mathbf{y^\prime} - B(x)\mathbf{y} = λA(x)\mathbf{y}, \quad…
