abstract = {<p style="text-align: justify;">We introduce two global-in-time domain decomposition methods, namely the Steklov-Poincare method and the Robin method, for solving a fluid-structure interaction system. These
methods allow us to formulate the coupled system as a space-time interface problem and apply
iterative algorithms directly to the evolutionary problem. Each time-dependent subdomain problem is solved independently, which enables the use of different time discretization schemes and
time step sizes in the subsystems. This leads to an efficient way of simulating time-dependent
phenomena. We present numerical tests for both non-physical and physical problems, with various mesh sizes and time step sizes to demonstrate the accuracy and efficiency of the proposed
methods.</p>},
