Abstract: For large values of the spectral parameter module, the asymptotics of solutions of the standard Sturm–Liouville equation with a piecewise-entire potential along an lying in the complex plane arbitrary shape curve with a finite number of points in which the solutions and (or) their derivatives undergo discontinuities independent of the spectral parameter is obtained. The eigenvalue problem is investigated for the case of decaying boundary conditions.

Keywords: equation along the curve, decision gap conditions, piecewise-entire potential, asymptotics of solutions, asymptotics of the spectrum.
