  "abstract": "The conductance ${\\cal G}$ of an Aharonov-Bohm interferometer (ABI), with a strongly correlated quantum dot on one arm, is expressed in terms of the dot Green function, $G_{dd}$, the magnetic flux $\\phi$ and the non-interacting parameters of the ABI. We show that one can extract $G_{dd}$ from the observed oscillations of ${\\cal G}$ with $\\phi$, for both closed and open ABI's. In the latter case, the phase shift $\\beta$ deduced from ${\\cal G} \\approx A+B\\cos(\\phi+\\beta)$ depends strongly on the ABI's parameters, and usually $\\beta \\ne \\pi/2$. These parameters may also reduce the Kondo temperature, eliminating the Kondo behavior.",
