Abstract: The crystallography of two-dimensional particle packings on flexible surfaces of spherical topology is investigated. Examples are viral capsids and crystalline vesicles. Computer simulations of dynamically triangulated surfaces are employed to study the shape and structure of lattice defects as a function of the Foppl-von Karman number gamma. We find that grain-boundary scars become much more fuzzy with increasing temperature, that the size of grain-boundary scars saturates with increasing vesicle radius, and that the buckling transition shifts to higher values of gamma due to the presence of scars.
