Summary: | <p>The Durfee square of a partition <em>λ, D(λ)</em>, is defined as the largest square contained in the shape of <em>λ</em>.</p><p>It was proved in [2] (cf. also [3]) that the size of <em>D(λ), d(λ)</em>, was related to the perfection of a certain module <em>M_λ</em> , an algebro-geometric object (cf. also [1], [4], [5]). The goal of this note is to propose a generalization of the notion of Durfee square to the case of a pair <em>(α, β)</em> of partitions.</p> |
