In physics, a quiver diagram is a graph representing the matter content of a gauge theory that describes D-branes on orbifolds. Each node of the graph corresponds to a factor ''U''(''N'') of the gauge group, and each link represents a field in the bifundamental representation :. The relevance of quiver diagrams for string theory was pointed out and studied by Michael Douglas and Greg Moore.〔D-branes, Quivers, and ALE Instantons http://arxiv.org/abs/hep-th/9603167〕 While string theorists use the words ''quiver diagram'', many of their colleagues in particle physics call these diagrams ''mooses''. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Quiver diagram」の詳細全文を読む スポンサード リンク
