Vector Riemann–Hilbert problem with almost periodic and meromorphic coefficients and applications
Vector Riemann–Hilbert problem with almost periodic and meromorphic coefficients and applications
The vector Riemann-Hilbert problem is analyzed when the entries of its matrix coefficient are meromorphic and almost periodic functions. Three cases for the meromorphic functions, when they have (i) a finite number of poles and zeros (rational functions), (ii) periodic poles and zeros, and (iii) an infinite number of non …
