Fiber products of elliptic surfaces with section and associated Kummer fibrations
Grzegorz Kapustka, Michal Kapustka
We investigate Calabi--Yau three folds which are small resolutions of fiber products of elliptic surfaces with section admitting reduced fibers. We start by the classification of a…
A cascade of determinantal Calabi--Yau threefolds
Grzegorz Kapustka, Michal Kapustka
We study Kustin--Miller unprojections of Calabi--Yau threefolds. As an application we work out the geometric properties of Calabi--Yau threefolds defined as linear sections of dete…
Primitive contractions of Calabi-Yau threefolds I
Grzegorz Kapustka, Michal Kapustka
We construct examples of primitive contractions of Calabi--Yau threefolds with exceptional locus being , , and smooth del Pezzo sur…
Equations of log del Pezzo surfaces of index 2
Grzegorz Kapustka, Michal Kapustka
Del Pezzo surfaces over C with log terminal singularities of index \le 2 were classified by Alekseev and Nikulin. In this paper, for each of these surfaces, we find an appropriate…
