Exact answers to approximate questions - noncommutative dipoles, open wilson lines and UV-IR duality

In this lecture, I put forward conjectures asserting that, in all noncommutative field theories. (1) open Wilson lines and their descendants constitute a complete set of interpolating operators of 'noncommutative dipoles', obeying dipole relation, (2) infrared dynamics of the noncommutative dipoles is dual to ultraviolet dynamics of the elementary noncommutative fields, and (3) open string field theory is a sort of noncommutative field theory, whose open Wilson lines are interpolating operators for closed strings. I substantiate these conjectures by various intuitive arguments and explicit computations of one- and two-loop Feynman diagrammatics. (authors)
