WebFeb 25, 2024 · In a strip, we consider an equation with the Euler–Poisson–Darboux operator containing a real positive parameter. We prove an energy inequality and the uniqueness of the classical solution of the Cauchy problem for the homogeneous equation, derive a formula for the solution, and establish its continuous dependence on the parameter. WebIn the case of finitely many gaps, Riemann–Hilbert formulations of the inverse problem have been considered before. For example, in [28, 29] Deconinck and Trogdon used a Riemann–Hilbert problem satisfied by Baker–Akhiezer functions to numerically compute finite gap solutions of the KdV equation.
