  Yang-Mills theory in 2+1 dimensions showed to be a research area yielding
firm results in theoretical physics when compared to lattice computations.
Recent analysis displayed astonishing agreement for the value of the string
tension and excellent comparison for the spectrum. This successful approach can
be put at test with a different theoretical framework that we devised in our
preceding work for the scalar field theory in the strong coupling limit. The
confirmations we get are really striking supporting it in full. As a by-product
we are also able to show how AdS/CFT approach, with a description using flux
tubes, is supported exactly as expected in the Isgur-Paton model with a
dimensionless correction factor for the ground state of the theory already
determined in lattice computations.
