The Weakly Special Conjecture for potential density
The Weakly Special Conjecture for potential density
Let be a smooth projective variety over a number field . A variety is weakly special if no finite étale cover of rationally dominates a positive-dimensional smooth projective variety of general type over . Weakly Special Conjecture. If is weakly special, then there is a finite extension such that is dense. This conjecture is presented as the converse to the prediction that dense rational points imply weak specialness; the paper's examples disprove it.
