摘要：The topological charge is constructed for SU(3) center vortex world-surfaces composed of elementary
squares on a hypercubic lattice. In distinction to the SU(2) case investigated previously,
it is necessary to devise a proper treatment of the color structure at vortex branchings, which arise
in the SU(3) case, but not for SU(2). The construction is used to evaluate the topological susceptibility
in the random vortex world-surface model of infrared Yang-Mills dynamics. Results for the
topological susceptibility are reported as a function of temperature, including both the conned
as well as the deconned phase.
