Özet
In this article we use immersions for representing the motions of massive composite membranes in background Lorentzian spacetimes. We construct an action for deriving the equation of motions by variation in modern differential geometric terms. By analyzing the top form line bundle structures we investigate and comment on the divisibility of a membrane in this setup. We also give as an example the motion of a membrane with spherical topology in Schwarzschild spacetime.
