Convergence of Iterations
Convergence is a central problem in both computer science and in population biology. Will a program terminate? Will a population go to an equilibrium? In general these questions are quite difficult – even unsolvable. In this paper we will concentrate on very simple iterations of the form
متن کاملCombinatorics of Polynomial Iterations
A complete description of the iterated monodromy groups of postcritically finite backward polynomial iterations is given in terms of their actions on rooted trees and automata generating them. We describe an iterative algorithm for finding kneading automata associated with post-critically finite topological polynomials and discuss some open questions about iterated monodromy groups of polynomials.
متن کاملIterations of ytterbium.
Although ytterbium was named by the Swiss chemist Jean de Marignac in 1878, his ‘element’ was subsequently split into two in 1905: ytterbium and lutetium. The atomic weight of the ‘new’ ytterbium was later published in 1907 — so when was ytterbium actually discovered? The story begins on 13 June 1726, more than 150 years before it first received its name. On that date an agreement was signed al...
متن کاملConsistent absence of BRAF mutations in salivary gland carcinomas
Introduction: Malignant salivary gland tumors are rare entities. Despite advances in surgery, radiation therapy and chemotherapy, the rate of the mortality and five-year survival has not been improved markedly over the last few decades. The activation of EGFR- RAS-RAF signaling pathway contributes to the initiation and progression of many human cancers, promising a key pathway for therapeutic m...
متن کاملAsynchronous Iterations for Enclosing Solutions Asynchronous Iterations for Enclosing Solutions
We consider asynchronous, parallel iterations for calculating enclosures of solutions of systems of nonlinear equations in IR n. Particularly, we will show how two classical theorems on the monotone convergence of some iterative methods for certain classes of nonlinear equations carry over to the asynchronous case.
