KW - (2+1)-dimensional nonlocal Fokas system, KP hierarchy reduction, multi-breather wave, high-order rogue wave, multi-bright-dark soliton.
AB - <p style="text-align: justify;">We study the (2+1)-dimensional nonlocal Fokas system by using the Hirota’s
bilinear method. Firstly, a general tau-function of Kadomtsev-Petviashvili (KP) hierarchy satisfied with the bilinear equation under nonzero boundary condition is derived by
considering differential relations and a variable transformation. Secondly, two Gram-type solutions are utilized to the construction of multi-breather, high-order rogue wave,
and multi-bright-dark soliton solutions. Then the corresponding parameter restrictions
of these solutions are given to satisfy with the complex conjugation symmetry. Furthermore, we find that if the parameter $p_{iI}$ takes different values, the rogue wave solution
can be classified as three types of states, such as dark-dark, four-peak and bright-bright
high-order rogue wave. If the parameter $c_i$ takes different values, the soliton solution
can be classified as three type of states, including the multi-dark, multi-bright-dark and
multi-bright solitons. By considering third-type of reduced tau-function to the Hirota’s
bilinear equations, we give the collisions between the high-order rogue wave and the
multi-bright-dark solitons on constant ($N$ is positive even) or periodic background ($N$ is
positive odd). In order to understand the dynamics behaviors of the obtained solutions
better, the various rich patterns are theoretically and graphically analyzed in detail.</p>
