Query: Points on singular Frobenius nonclassical curves   In 1990, Hefez and Voloch proved that the number of $F_q$-rational points on
a nonsingular plane $q$-Frobenius nonclassical curve of degree $d$ is $N =
d(q-d+2)$. We address these curves in the singular setting. In particular, we
prove that $d(q-d + 2)$ is a lower bound on the number of $F_q$-rational points
on such curves of degree $d$.
