Query: Involutions on a surface of general type with $p_g=q=0$, $K^2=7$   In this paper we study on the involution on minimal surfaces of general type
with $p_g=q=0$ and $K^2=7$. We focus on the classification of the birational
models of the quotient surfaces and their branch divisors induced by an
involution.
