A combinatorial realization of Kirillov-Reshetikhin crystals for type E arising from translations
Abstract
The main purpose of this paper is to give a combinatorial realization of Kirillov-Reshetikhin (KR simply) crystals for type with a minuscule node and . To do this, we describe explicitly the crystal of the quantum nilpotent subalgebra associated with the translation by the negative of the -th fundamental weight. Then the crystal can be extended as an affine crystal, in which a certain subcrystal characterized by the -statistic is isomorphic to as an affine crystal, where is also realized precisely in terms of triple and quadruple paths.
