The Dual Nest for Degenerate Yoccoz Puzzles
نویسنده
چکیده
The Yoccoz puzzle is a fundamental tool in Holomorphic Dynamics. The original combinatorial argument by Yoccoz, based on the BrannerHubbard tableau, counts the preimages of a non-degenerate annulus in the puzzle. However, in some important new applications of the puzzle (notably, matings of quadratic polynomials) there is no non-degenerate annulus. We develop a general combinatorial argument to handle this situation. It allows us to derive corollaries, such as the local connectedness of the Julia set, for suitable families of rational maps.

Parameter Scaling for the Fibonacci Point
We prove geometric and scaling results for the real Fibonacci parameter value in the quadratic family z 7→ z + c. The principal nest of the Yoccoz parapuzzle pieces has rescaled asymptotic geometry equal to the filled-in Julia set of z 7→ z − 1. The modulus of two such successive parapuzzle pieces increases at a linear rate. Finally, we prove a “hairiness” theorem for the Mandelbrot set at the ...
متن کاملLocal Connectivity of Julia Sets
We prove that the Julia set J(f) of at most finitely renormalizable unicritical polynomial f : z 7→ z + c with all periodic points repelling is locally connected. (For d = 2 it was proved by Yoccoz around 1990.) It follows from a priori bounds in a modified Principle Nest of puzzle pieces. The proof of a priori bounds makes use of new analytic tools developed in [KL] that give control of moduli...
متن کاملConductivity Coefficient Modeling in Degenerate and Non-Degenerate Modes on GNSs
Carbon nanoscrolls (CNSs) with tubular structure similar to the open multiwall carbonnanotube have been of hot debate during recent years. Due to its unique property, Graphene Nanoscroll (GNS) have attracted many research groups’ attention and have been used by them. They specially studied on energy storage devices such as batteries and super capacitors. These devices can be schematically...
متن کاملMonodromy problem for the degenerate critical points
For the polynomial planar vector fields with a hyperbolic or nilpotent critical point at the origin, the monodromy problem has been solved, but for the strongly degenerate critical points this problem is still open. When the critical point is monodromic, the stability problem or the center- focus problem is an open problem too. In this paper we will consider the polynomial planar vector fields ...
متن کاملDesigning Of Degenerate Primers-Based Polymerase Chain Reaction (PCR) For Amplification Of WD40 Repeat-Containing Proteins Using Local Allignment Search Method
Degenerate primers-based polymerase chain reaction (PCR) are commonly used for isolation of unidentified gene sequences in related organisms. For designing the degenerate primers, we propose the use of local alignment search method for searching the conserved regions long enough to design an acceptable primer pair. To test this method, a WD40 repeat-containing domain protein from Beauveria bass...
