Dense semigroups of triangular matrices

Mohammad Javaheri

Let $K = R$ or $C$ , and $T_{n} (K)$ be the set of $n \times n$ lower triangular matrices with entries in $K$ . We show that $T_{n} (K)$ …

Maximally transitive semigroups of $n \times n$ matrices

Mohammad Javaheri

We prove that, in both real and complex cases, there exists a pair of matrices that generates a dense subsemigroup of the set of $n \times n$ matrices.

Semigroups of real functions with dense orbits

Mohammad Javaheri

Let $F_{I} = {f : I \to I ∣ f (x) = (A x + B) / (C x + D); A D - B C \neq = 0}$ , where $I$ is an interval. For $x \in I$ , let $Ω_{x}$ be the orbit of $x$ under the action of the semigroup of f…

Semigroups of matrices with dense orbits

Mohammad Javaheri

We give examples of $n \times n$ matrices $A$ and $B$ over the filed $K = R$ or $C$ such that for almost every column vector $x \in K^{n}$ , the orbi…
