FIXED POINTS OF POLYNOMIALS OVER DIVISION RINGS

چکیده
We study the discrete dynamics of standard (or left) polynomials $f(x)$ over division rings $D$. define their fixed points to be $\lambda \in D$ for which $f^{\circ n}(\lambda)=\lambda$ any $n \mathbb{N}$, where n}(x)$ is defined recursively by n}(x)=f(f^{\circ (n-1)}(x))$ and 1}(x)=f(x)$. Periodic are similarly defined. prove that $\lambda$ a point if only $f(\lambda)=\lambda$, enables use known results from theory polynomial equations, conclude degree $m \geq 2$ has at most $m$ conjugacy classes points. also consider arbitrary periodic points, show in general, they do not behave as commutative case. provide sufficient condition expected.

Wedderburn Polynomials over Division Rings
A Wedderburn polynomial over a division ring K is a minimal polynomial of an algebraic subset of K. Special cases of such polynomials include, for instance, the minimal polynomials (over the center F = Z(K)) of elements of K that are algebraic over F . In this note, we give a survey on some of our ongoing work on the structure theory of Wedderburn polynomials. Throughout the note, we work in th...
متن کاملOn nest modules of matrices over division rings
Let $ m , n in mathbb{N}$, $D$ be a division ring, and $M_{m times n}(D)$ denote the bimodule of all $m times n$ matrices with entries from $D$. First, we characterize one-sided submodules of $M_{m times n}(D)$ in terms of left row reduced echelon or right column reduced echelon matrices with entries from $D$. Next, we introduce the notion of a nest module of matrices with entries from $D$. We ...
متن کاملTriangularization over finite-dimensional division rings using the reduced trace
In this paper we study triangularization of collections of matrices whose entries come from a finite-dimensional division ring. First, we give a generalization of Guralnick's theorem to the case of finite-dimensional division rings and then we show that in this case the reduced trace function is a suitable alternative for trace function by presenting two triangularization results. The first one...
