Crepant resolutions of four-dimensional finite quotients

Dominik Burek, Sławomir Cynk

We give counterexamples to the conjecture of Dais-Henk-Ziegler on projective crepant resolutions of complete-intersection quotient singularities. For finite $G\subset\operatorname{…

An elliptic Calabi-Yau threefold of Mordell-Weil rank twelve

Dominik Burek

We construct a smooth projective Calabi-Yau threefold with a flat elliptic fibration of Mordell-Weil rank twelve and Hodge numbers . The construction star…

Crepant resolutions of fiber products and Kummer fibrations of rational elliptic surfaces with non-reduced fibers

Dominik Burek, Sławomir Cynk

Let and be rational elliptic surfaces with section over an algebraically closed field of characteristic zero, and let . We determine the…

Fixed-locus relations and purely non-symplectic automorphisms of order 6 on K3 surfaces

Dominik Burek

We study relations between invariants of the fixed loci of purely non-symplectic automorphisms of surfaces. We obtain these relations by comparing the stringy Euler characteri…

Zeta function of some Kummer Calabi-Yau 3-folds

Dominik Burek

We compute Hodge numbers and zeta function of a Kummer Calabi-Yau 3-folds introduced by M. Andreatta and J. Wiśniewski in arXiv:0804.4611 and investigated by M. Donten-Bury in arXi…

Higher dimensional analogon of Borcea-Voisin Calabi-Yau manifolds, their Hodge numbers and -functions

Dominik Burek

We construct a series of examples of Calabi-Yau manifolds in an arbitrary dimension and compute the main invariants. In particular, we give higher dimensional generalization of Bor…

Higher dimensional Calabi-Yau manifolds of Kummer type

Dominik Burek

Based on Cynk-Hulek method we construct complex Calabi-Yau varieties of arbitrary dimensions using elliptic curves with automorphism of order 6. Also we give formulas for Hodge num…

A new upper bound for numbers with the Lehmer property and its application to repunit numbers

Dominik Burek, Błażej Żmija

A composite positive integer has the Lehmer property if divides where is an Euler totient function. In this note we shall prove that if has the Lehmer pro…

Rigid realizations of modular forms in Calabi--Yau threefolds

Dominik Burek

We construct examples of modular rigid Calabi--Yau threefolds, which give a realization of some new weight 4 cusp forms.

Hodge Numbers of Generalised Borcea-Voisin Threefolds

Dominik Burek

We shall reproof formulas for the Hodge numbers of Calabi-Yau threefolds of Borcea-Voisin type constructed by A. Cattaneo and A. Garbagnati, using the orbifold cohomology formula a…
