Standard stable Horikawa surfaces

Julie Rana, Sönke Rollenske

We consider the stable compactification $H ˉ$ of the moduli space of Horikawa surfaces with $K_{X}^{2} = 2 p_{g} (X) - 4$ . When $K_{X}^{2} = 8 ℓ$ we show that the closures of th…

I-surfaces with one T-singularity

Marco Franciosi, Rita Pardini, Julie Rana +1

We classify normal stable surfaces with $K_{X}^{2} = 1$ , $p_{g} = 2$ and $q = 0$ with a unique singular point which is a non-canonical T-singularity, thus exhibiting two divisors in the ma…

Equations of $M_{0, n}$

Leonid Monin, Julie Rana

Following work of Keel and Tevelev, we give explicit polynomials in the Cox ring of $P^{1} \times \dots \times P^{n - 3}$ that, conjecturally, determine $\overline{M}_{0…
