Abstract

We construct a minimal complex surface of general type with pg=0p_g=0, K2=4K^2 =4, and π1=Z/2Z\pi_1=\mathbb{Z}/2\mathbb{Z} using a rational blow-down surgery and a Q\mathbb{Q}-Gorenstein smoothing theory. In a similar fashion, we also construct a symplectic 4-manifold with b2+=1b_2^+=1, K2=5K^2=5, and π1=Z/2Z\pi_1=\mathbb{Z}/2\mathbb{Z}.
