Multiple-Pole Solutions to a Semidiscrete Modified Korteweg-de Vries Equation

الملخص EN

Multiple-pole soliton solutions to a semidiscrete modified Korteweg-de Vries equation are derived by virtue of the Riemann-Hilbert problem with higher-order zeros.

A different symmetry condition is introduced to build the nonregular Riemann-Hilbert problem.

The simplest multiple-pole soliton solution is presented.

The dynamics of the solitons are studied.
