  • Inverse Scattering Theory for Schrödinger Operators with Steplike Potentials 
    Egorova, I.; Gladka, Z.; Lange, T.L.; Teschl, G. (Журнал математической физики, анализа, геометрии, 2015)
    We study the direct and inverse scattering problem for the one-dimensional Schrödinger equation with steplike potentials. We give necessary and sufficient conditions for the scattering data to correspond to a potential ...
  • Long-Time Asymptotics for the Toda Shock Problem: Non-Overlapping Spectra 
    Egorova, I.; Michor, J.; Teschl, G. (Журнал математической физики, анализа, геометрии, 2018)
    We derive the long-time asymptotics for the Toda shock problem using the nonlinear steepest descent analysis for oscillatory Riemann-Hilbert factorization problems. We show that the half-plane of space/time variables splits ...
  • On the Form of Dispersive Shock Waves of the Korteweg-de Vries Equation 
    Egorova, I.; Gladka, Z.; Teschl, G. (Журнал математической физики, анализа, геометрии, 2016)
    We show that the long-time behavior of solutions to the Korteweg{de Vries shock problem can be described as a slowly modulated one-gap solution in the dispersive shock region. The modulus of the elliptic function (i.e., ...
  • Scattering Theory for Jacobi Operators with General Step-Like Quasiperiodic Background 
    Egorova, I.; Michor, J.; Teschl, G. (Журнал математической физики, анализа, геометрии, 2008)
    We develop direct and inverse scattering theory for Jacobi operators with step-like coeffcients which are asymptotically close to different finite-gap quasiperiodic coeffcients on di erent sides. We give a complete ...
