Reducible hyperplane sections of threefolds: two components of sectional genus zero / A. Lanteri, A.L. Tironi. - In: KODAI MATHEMATICAL JOURNAL. - ISSN 0386-5991. - 27:3(2004), pp. 299-320.
Abstract:
By using adjunction theory, we describe the smooth complex projective threefolds admitting a simple normal crossing divisor of the form A+B among their hyperplane sections, both components A and B being smooth surfaces with sectional genus 0, and one of them being nef or at worst an exceptional divisor of the first reduction mapping.
