Outline of Final Research Achievements |
In this research the author has studied asymptotic behavior of the distributions of the eigenvalues of Laplacians (the eigenfrequencies) on fractals and has proved the following assertions: Connes' trace theorem, which characterizes the notion of volume as an operator-theoretic paraphrase of eigenvalue asymptotics, holds for a large class of Laplacians on fractals including the case of the measurable Riemannian structure on the Sierpinski gasket, and surface area can be also characterized in a similar manner. Moreover, for the measurable Riemannian structure on a classical fractal called the Apollonian gasket, the author has proved several fundamental facts such as the self-adjointness of the associated Laplacian, the discreteness of the eigenvalue distribution of the Laplacian, and estimates of the smallest eigenvalue.
