Sandpiles, spanning trees, and plane duality
Melody Chan, Darren Glass, Matthew Macauley +3
Let G be a connected, loopless multigraph. The sandpile group of G is a finite abelian group associated to G whose order is equal to the number of spanning trees in G. Holroyd et a…

A simply connected numerical Godeaux surface with ample canonical class
I. Dolgachev, C. Werner
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 p…

A surface of general type with \( p_g =q =0, K^2 =1 \)
Caryn Werner
We construct a surface of general type with invariants \( χ= K^2 = 1 \) and torsion group \( \Bbb{Z}/{2} \). We use a double plane construction by finding a plane curve with certai…
