      abstract     = {The deformation of thin spherical shells by applying an
                      external pressure or by reducing the volume is studied by
                      computer simulations and scaling arguments. The shape of the
                      deformed shells depends on the deformation rate, the reduced
                      volume V/V-0 and the Foppl-von Karman number gamma. For slow
                      deformations the shell attains its ground state, a shell
                      with a single indentation, whereas for large deformation
                      rates the shell appears crumpled with many indentations. The
                      rim of the single indentation undergoes a shape transition
                      from smooth to polygonal for gamma similar or equal to
                      7000(Delta V/V-0)(-3/4). For the smooth rim the elastic
                      energy scales like gamma(1/4) whereas for the polygonal
                      indentation we find a much smaller exponent, even smaller
                      than the exponent 1/6 that is predicted for stretching
                      ridges. The relaxation of a shell with multiple indentations
                      towards the ground state follows an Ostwald ripening type of
                      pathway and depends on the compression rate and on the
                      Foppl-von Karman number. The number of indentations
                      decreases as a power law with time t following N-ind similar
                      to t(-0.375) for gamma = 8 x 10(3) and gamma = 8 x 10(4)
                      whereas for gamma = 8 x 10(5) the relaxation time is longer
                      than the simulation time.},
