The moduli space of stable surfaces with K^2=1 and \chi=3 has at least two irreducible components that contain surfaces with T-singularities. We show that the two known components intersect transversally in a divisor. Moreover, we exhibit other new boundary divisors and study how they intersect one another.

Abstract
The moduli space of stable surfaces with K^2=1 and \chi=3 has at least two irreducible components that contain surfaces with T-singularities. We show that the two known components intersect transversally in a divisor. Moreover, we exhibit other new boundary divisors and study how they intersect one another.File in questo prodotto:
