In various biological systems and small scale technological applications particles
transiently bind to a cylindrical surface. Upon unbinding the particles diffuse in the
vicinal bulk before rebinding to the surface. Such bulk-mediated excursions give rise to
an effective surface translation, for which we here derive and discuss the dynamic
equations, including additional surface diffusion. We discuss the time evolution of the
number of surface-bound particles, the effective surface mean squared displacement, and
the surface propagator. In particular, we observe sub- and superdiffusive regimes. A
plateau of the surface mean-squared displacement reflects a stalling of the surface
diffusion at longer times. Finally, the corresponding first passage problem for the
cylindrical geometry is analysed.
