      abstract     = {We present a Brownian dynamics theory with full
                      hydrodynamics (Stokesian dynamics) for a Gaussian polymer
                      chain embedded in a liquid membrane which is surrounded by
                      bulk solvent and walls. The mobility tensors are derived in
                      Fourier space for the two geometries, namely, a free
                      membrane embedded in a bulk fluid, and a membrane sandwiched
                      by the two walls. Within the preaveraging approximation, a
                      new expression for the diffusion coefficient of the polymer
                      is obtained for the free-membrane geometry. We also carry
                      out a Rouse normal mode analysis to obtain the relaxation
                      time and the dynamical structure factor. For large polymer
                      size, both quantities show Zimm-like behavior in the
                      free-membrane case, whereas they are Rouse-like for the
                      sandwiched membrane geometry. We use the scaling argument to
                      discuss the effect of excluded-volume interactions on the
                      polymer relaxation time.},
