Torsion order and irrationality of complete intersections

Jan Lange, Guoyun Zhang

We provide new logarithmic lower bounds for the torsion order of a very general complete intersection in projective space as well as a very general hypersurface in products of proj…

Cohomological rank functions and surfaces of general type with $p_{g} = q = 2$

Jiabin Du, Zhi Jiang, Guoyun Zhang

We classify minimal surfaces $S$ with $p_{g} = q = 2$ and $K_{S}^{2} = 5$ or $6$ .
