Research Abstract

準結晶等の非周期的離散構造は研究対象としては統一的な扱いの難しいものであるが自己相似性をもち特定パターンが正の頻度で繰り返す場合には、置換規則の幾何学的実現、数系タイルの双対タイル張りなどを通じて数学的研究が進んでいる。対応する自己相似タイル張りの力学系は強エルゴード的となり、そのスペクトル型の研究も重要である。本研究では、数系タイル力学系が純離散スペクトルを持つか否かという問題と密接に関連する数系の有限性、弱有限性について様々な結果を得た。特に有限性を特徴付けるために、シフト基数系を導入したことが今回の研究の最大の成果である。これは簡単な格子状の離散力学系ではあるが、「良い」タイル張り力学系のモジュライ空間のような概念となっており更なる研究の発展が必要とされている重要なものである。
