ILLUSTRATIVE EXAMPLE OF HOW QUARK-HADRON DUALITY MIGHT WORK

We discuss the issue of the local quark-hadron duality at high energie s in two- and four-dimensional QCD. A mechanism of the dynamical reali zation of the quark-hadron duality in two-dimensional QCD in the limit of a large number of colors, N-c-->infinity (the 't Hooft model), is considered. A similar-mechanism of dynamical smearing may be relevant in four-dimensional QCD. Although particular details of our results ar e model dependent, the general features of the duality implementation conjectured previously get further support.
