Rational self-maps of projective surfaces with a regular iterate

Sina Saleh

We show that if $Φ : X ⇢ X$ is a dominant rational self-map of a projective surface $X$ over $C$ with a regular and non-invertible iterate $Φ^{n}$ , then we can…

Zariski dense orbits for endomorphisms of a power of the additive group scheme defined over finite fields

Dragos Ghioca, Sina Saleh

We prove the Zariski dense orbit conjecture in positive characteristic for endomorphisms of $G_{a}^{N}$ defined over $F_{p}$ .

Zariski dense orbits for regular self-maps of split semiabelian varieties in positive characteristic

Dragos Ghioca, Sina Saleh

We prove the Zariski dense orbit conjecture in positive characteristic for regular self-maps of split semiabelian varieties.

On sparsity of representations of polynomials as linear combinations of exponential functions

Dragos Ghioca, Alina Ostafe, Sina Saleh +1

Given an integer $g$ and also some given integers $m$ (sufficiently large) and $c_{1}, \dots, c_{m}$ , we show that the number of all non-negative integers $n \leq M$ with the property tha…

A sparsity result for the Dynamical Mordell-Lang Conjecture in positive characteristic

Dragos Ghioca, Alina Ostafe, Sina Saleh +1

We prove a quantitative partial result in support of the Dynamical Mordell-Lang Conjecture (also known as the DML conjecture) in positive characteristic. More precisely, we show th…
