The Image of an Arboreal Galois Representation
Much is known regarding images of p-adic Galois representations coming from subquotients of étale cohomology groups of varieties over number fields. In particular, the Mumford-Tate conjecture gives them up to subgroups of finite index, and has been proved in many cases by Serre. In the analogous situation of arboreal Galois representations little is known. In this paper we give a conjectural de...
متن کاملArboreal Galois Representations
Let GQ be the absolute Galois group of Q, and let T be the complete rooted d-ary tree, where d ≥ 2. In this article we study “arboreal” representations of GQ into the automorphism group of T , particularly in the case d = 2. In doing so, we propose a parallel to the well-developed and powerful theory of linear p-adic representations of GQ. We first give some methods of constructing arboreal rep...
متن کاملDynamics of postcritically bounded polynomial semigroups
We investigate the dynamics of semigroups generated by polynomial maps on the Riemann sphere such that the postcritical set in the complex plane is bounded. Moreover, we investigate the associated random dynamics of polynomials. We show that for such a polynomial semigroup, if A and B are two connected components of the Julia set, then one of A and B surrounds the other. A criterion for the Jul...
متن کاملFinite groups admitting a connected cubic integral bi-Cayley graph
A graph is called integral if all eigenvalues of its adjacency matrix are integers. Given a subset $S$ of a finite group $G$, the bi-Cayley graph $BCay(G,S)$ is a graph with vertex set $Gtimes{1,2}$ and edge set ${{(x,1),(sx,2)}mid sin S, xin G}$. In this paper, we classify all finite groups admitting a connected cubic integral bi-Cayley graph.
متن کاملCanonical representation for approximating solution of fuzzy polynomial equations
In this paper, the concept of canonical representation is proposed to find fuzzy roots of fuzzy polynomial equations. We transform fuzzy polynomial equations to system of crisp polynomial equations, this transformation is perform by using canonical representation based on three parameters Value, Ambiguity and Fuzziness.
