Abstract


I study the correlator of two parallel Wilson lines
in two-dimensional noncommutative
Yang-Mills theory, following
two different approaches. I first consider a perturbative
expansion in the large-N limit and resum all planar diagrams.
The second approach is non-perturbative: the Morita
equivalence, mapping the
two open lines on the noncommutative torus (which eventually gets
decompacted)
in two closed Wilson loops winding around the dual 
commutative torus, is
exploited.
