Non-holomorphic Lefschetz fibrations with $(- 1)$ -sections

Noriyuki Hamada, Ryoma Kobayashi, Naoyuki Monden

We construct two types of non-holomorphic Lefschetz fibrations over $S^{2}$ with $(- 1)$ -sections ---hence, they are fiber sum indecomposable--- by giving the corresponding positive r…

Sections of the Matsumoto-Cadavid-Korkmaz Lefschetz fibration

Noriyuki Hamada

We give a maximal set of disjoint $(- 1)$ -sections of the well-known Lefschetz fibration constructed by Matsumoto, Cadavid and Korkmaz. In fact, we obtain several such sets for a fi…

Topology of holomorphic Lefschetz pencils on the four-torus

Noriyuki Hamada, Kenta Hayano

In this paper we discuss topological properties of holomorphic Lefschetz pencils on the four-torus. Relying on the theory of moduli spaces of polarized abelian surfaces, we first p…
