N2 - The conductance G of an Aharonov-Bohm interferometer (ABI), with a strongly correlated quantum dot on one arm, is expressed in terms of the dot Green function, Gdd, the magnetic flux and the noninteracting parameters of the ABI {Jμν}. At T=0, Fermi liquid theory yields the exact dependence of G. We show that one can extract Gdd from the observed G (), for both closed and open ABI's. In the latter case, the phase shift β deduced from G A+B cos (+β) depends strongly on the { Jμν } 's, and usually β π 2. The {Jμν} 's may also reduce the Kondo temperature.
