  The purpose of this study is to show the relations between monopoles
instantons and Chiral symmetry breaking. First, in order to show the relation
between instantons and monopoles, we generate configurations, adding monopoles
by a monopole creation operator. Then, we count the number of fermion zero
modes in the configurations using Overlap fermions as a tool. As a result we
find that one monopole with plus one charge and one anti-monopole with minus
one charge make one instanton of charge plus or minus one. We have already
reported these results elsewhere. In addition, in this report, the relation
between the additional monopoles and Chiral symmetry breaking is discussed. We
compute the Chiral condensate, the pseudo-scalar mass, and the pion decay
constant. Preliminary results show that the additional monopoles do affect
Chiral symmetry breaking.
