Query: Universality check of Abelian Monopoles   We study the Abelian projected SU(2) lattice gauge theory after gauge fixing
to the maximally Abelian gauge (MAG). In order to check the universality of the
Abelian dominance we employ the tadpole improved tree level (TI) action. We
show that the density of monopoles in the largest cluster (the IR component) is
finite in the continuum limit which is approximated already at relatively large
lattice spacing. The value itself is smaller than in the case of Wilson action.
We present results for the ratio of the Abelian to non-Abelian string tension
for both Wilson and TI actions for a number of lattice spacings in the range
0.06 fm < a < 0.35 fm. These results show that the ratio is between 0.9 and
0.95 for all considered values of lattice couplings and both actions. We
compare the properties of the monopole clusters in two gauges - in MAG and in
the Laplacian Abelian gauge (LAG). Whereas in MAG the infrared component of the
monopole density shows a good convergence to the continuum limit, we find that
in LAG it is even not clear whether a finite limit exists.
