Izvirni znanstveni članek
Oznake: quilts;alternating sign matrices;Dedekind numbers;distributive lattice;
In this paper, we present new objects, quilts of alternating sign matrices with respect to two given posets. Quilts generalize several commonly used concepts in mathematics. For example, the rank function on submatrices of a matrix gives rise to a quilt with respect to two Boolean lattices. When the ...
