Maximally nodal sextic surfaces and linear determinantal representations

Yonghwa Cho

We prove that every maximally nodal sextic surface\,(with 65 nodes) $X \subset P_{C}^{3}$ contains a symmetric half-even set of nodes of cardinality 35. It follows…

Counting $h^{0} (D)$ on primary Burniat surfaces

Yonghwa Cho

We study the cohomology of divisors on a Burniat surface $X$ with $K_{X}^{2} = 6$ . We provide an algorithm for computing the cohomology groups of arbitrary divisors on $X$ . As an applica…

Positivity of double point divisors

Yonghwa Cho, Jinhyung Park

The non-isomorphic locus of a general projection from an embedded smooth projective variety to a hypersurface moves in a linear system of an effective divisor which we call the dou…
