Query: Unirationality of del Pezzo surfaces of degree two over finite fields   We prove that every del Pezzo surface of degree two over a finite field is
unirational, building on the work of Manin and an extension by Salgado, Testa,
and V\'arilly-Alvarado, who had proved this for all but three surfaces. Over
general fields of characteristic not equal to two, we state sufficient
conditions for a del Pezzo surface of degree two to be unirational.
