Description

In this talk, I will introduce a large class of transcendental entire maps to which we can transfer several central results in polynomial dynamics; this includes many of the available results on rigidity and density of hyperbolicity. This transfer is done via our main tool: dynamically meaningful polynomial approximations, which we establish in the near-degenerate regime. If time permits, I will also outline further implications for Transcendental Thurston Theory. Based on joint work, partially in progress, with Dzmitry Dudko.
