We prove that a recent construction of a numerical Godeaux surface due to P. Craighero and R. Gattazzo is simply connected, and show how to realize their construction as a double plane. By proving that the surface contains no (-2)-curves, we obtain that this is the first example of a simply connected surface with vanishing geometric genus and ample canonical class. 

The Craighero–Gattazzo surface is simply connected

We show that the Craighero–Gattazzo surface, the minimal resolution of an explicit complex quintic surface with four elliptic singularities, is simply connected. This was conjectured by Dolgachev and

Canonical rings of Gorenstein stable Godeaux surfaces

Extending the description of canonical rings from Reid (J Fac Sci Univ Tokyo Sect IA Math 25(1):75–92, 1978) we show that every Gorenstein stable Godeaux surface with torsion of order at least 3 is

Bloch's conjecture on surfaces of general type with an involution

In this short note we prove that the Bloch's conjecture holds for a surface of general type of numerical Godeaux type or some class of numerical Campedelli type, with geometric genus zero equipped

Degenerations Of Godeaux Surfaces And Exceptional Vector Bundles

A recent construction of Hacking relates the classification of stable vector bundles on a surface of general type with $p_g = 0$ and the boundary of the moduli space of deformations of the surface.

Numerical Godeaux surfaces with an involution

Minimal algebraic surfaces of general type with the smallest possible invariants have geometric genus zero and K 2 = 1 and are usually called numerical Godeauz surfaces. Although they have been

Gorenstein stable Godeaux surfaces

We classify Gorenstein stable numerical Godeaux surfaces with worse than canonical singularities and compute their fundamental groups.

Chow groups of conic bundles in $\mathbb P^5$ and the Generalised Bloch's conjecture

Consider the Fano surface of a conic bundle embedded in $\mathbb P^5$. Let $i$ denote the natural involution acting on this surface. In this note we provide an obstruction to the identity action of

On the class of projective surfaces of general type

Let S be a smooth complex projective surface of general type, H be a very ample divisor on S and m(S, H) be the class of (S, H). In this paper, we study a lower bound for m(S, H)− 3H2 and we improve

Generalised Bloch's conjecture on surfaces of general type with involution

In this short note we prove that an involution on certain examples of surfaces of general type with $p_g=0$, acts as identity on the Chow group of zero cycles of the relevant surface.

A surface of general type with pg=q=0,K2=1

We construct a surface of general type with invariants \( \chi = K^2 = 1 \) and torsion group \( \Bbb{Z}/{2} \). We use a double plane construction by finding a plane curve with certain
