Abstract
Cheeger-type inequalities are derived relating various vertex isoperimetric constants to a Poincare-type functional constant, denoted by lambda(infini ty). This approach refines results relating the spectral gap of a graph to the so-called magnification of a graph. A concentration result involving la mbda(infinity) is also derived.
