英文摘要: This research project is the project belonging to the intersection field of multi-domains in the science research, such as the computer science, mathematics and nonlinear science and so on.We take the computers as our experiment platforms. We do our research work based on the theories of chaotic dynamics, fractal geometry and computer graphics. The main tasks include that the construction of new symmetrical iteration mappings and IFSs in the Euclidean plane and the hyperbolic plane or on the spherical surface, the investigation of the estimate arithmetic of the dynamic characteristic of the symmetric mappings on the sphere surface, the investigation of the construction of the chaotic attractors and the filled-in Julia sets on the upper half spherical surface in the any projected plane containing the origin; the investigation of the construction of the chaotic attractors, the filled-in Julia sets and fractals on the spherical surface from the plane mappings and IFSs, the investigation of the construction of the hyperbolic limit disks by asymmetric pictures and the investigation of the construction of plane tilings with different structures by the mappings with the non-equidistant cyclic windows under the same set of the parameters. The research production is not only useful to develop the research of the visualiz
