A complex surface of general type with p_g=0, K^2=2 and H_1=Z/2Z, Z/3Z
Yongnam Lee, Jongil Park
As the sequel to [3], we construct a minimal complex surface of general type with p_g=0, K^2=2 and H_1=Z/2Z using a rational blow-down surgery and Q-Gorenstein smoothing theory. We…

A construction of Horikawa surface via Q-Gorenstein smoothings
Yongnam Lee, Jongil Park
In this article we prove that Fintushel-Stern's construction of Horikawa surface, which is obtained from an elliptic surface via a rational blow-down surgery in smooth category, ca…

Log minimal model program for the moduli space of stable curves of genus three
Donghoon Hyeon, Yongnam Lee
In this paper, we completely work out the log minimal model program for the moduli space of stable curves of genus three. We employ a rational multiple of the divisor of s…
