Research Abstract

We intended to develop parallel researches with the paper [S1] for fractal waves (i.e. musical passages, sounds of voices, or picture data with some noises) by finding some effective topological invariants. Although we did not succeed to find the invariants, we summarized our mathematical foundation in [S4], and using the Work Station, which was equipped by this grant, we listed up all fractals in [S3] by the way used in [S2] and found two different kinds of fractals never appeared among CG's in their book. On the other hand, we believe that the space studied in [S5], which is the countable topological product of a space consisting of three points with non T_1-topology, will give some strong influences for our further studies concerning this research.
