Outline of Final Research Achievements

We were able to advance research on a wide range of topics related to dynamical systems with self-similar structures. Here we list major achievements: Garcia entropy calculation algorithm of Bernoulli convolution, Self-similar structures corresponding to rational-based number systems, Moebius orthogonality of strong frequency sequences, a strong aperiodic tiling consisting of one type of tile in hyperbolic space, corona limit in a general framework and investigate its fundamental properties, normality in number theory from the point of view of dynamical systems: piecewise linear map Pisot slopes having identical generic points.

Academic Significance and Societal Importance of the Research Achievements

成果は査読付きの数学の専門誌に掲載された。これらの一般化の方向で共同研究は引き続き行われている。コロナ極限については研究方向が定まり、非周期タイル張りの場合に関心が向かっている。Bernoulli 畳み込みについては、代数的パラメータについての世界的に多くの研究が進んでいる。Sarnak 予想についても多くの関連研究が次々に発表されている。
