  We address the question of whether the low modes of the Dirac operator are
caused by topological objects such as instantons in SU(N) gauge theories. We
study the pseudo-scalar density of these modes, finding the size distributions
of the instantons, and comparing it with the underlying gauge field. We find
that, although the near-zero modes of the Dirac operator depend on topology for
all N, their small instanton content decreases as N increases.
