Let $\Omega $ be a bounded open set of ${\mathbb {R}^ n}\;(n\geq 1) $ with" fractal"
boundary $\Gamma $. We extend Hermann Weyl's classical theorem by establishing a …

This monograph presents recent and new ideas arising from the study of problems of planar
fluid dynamics, and which are interesting from the point of view of geometric function theory …

A fractal drum is a bounded open subset of R. m with a fractal boundary. A difficult problem
is to describe the relationship between the shape (geo metry) of the drum and its sound (its …
