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…

Convergence of Ricci flow on $R^{2}$ to flat space

James Isenberg, Mohammad Javaheri

We prove that, starting at an initial metric $g (0) = e^{2 u_{0}} (d x^{2} + d y^{2})$ on $R^{2}$ with bounded scalar curvature and bounded $u_{0}$ , the Ricci flow $\partial_t g(t)=-R_{g(t)}…

On a property of plane curves

Mohammad Javaheri

Let $γ : [0, 1] \to [0, 1]^{2}$ be a continuous curve such that $γ (0) = (0, 0)$ , $γ (1) = (1, 1)$ , and $γ (t) \in (0, 1)^{2}$ for all $t \in (0, 1)$ . We prove that, for each $n \in N$ , ther…

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…
