报告摘要: In this talk, some basic materials on fractal geometry and dynamical systems will be introduced. Further, we talk about the construction of a generalized family of transcendental (non-polynomial entire) functions, where the Hausdorff dimension and the packing dimension of the Julia sets are equal to one, there exist multiply connected wandering domains, the dynamics can be completed described, and for any non-negative number s, there is a function taken from this family with the order of growth s. Baker proved that the Hausdorff dimension of the transcendental function is no less than one in 1975, the minimum value was obtained via an elegant construction by Bishop in 2018. The order of growth is zero in Bishop's construction, the family of functions here have arbitrarily positive or even infinite order of growth.
