I-surfaces with one T-singularity

Algebraic Geometry 2020-12-11 v1

Abstract

We classify normal stable surfaces with KX2=1K_X^2 = 1, pg=2p_g = 2 and q=0q=0 with a unique singular point which is a non-canonical T-singularity, thus exhibiting two divisors in the main component and a new irreducible component of the moduli space of stable surfaces \gothM1,3\overline\gothM_{1,3}.
