Берглунда-Хубша и многогранники Батырева</b><b><br>

In this article, we consider the phenomenon of complete coincidence
of the key properties of pairs of Calabi-Yau manifolds realized as
hypersurfaces in two different weighted projective spaces. More
precisely, the first manifold in such a pair is realized as a
hypersurface in a weighted projective space, and the second as a
hypersurface in the orbifold of another weighted projective space.
The two manifolds in each pair have the same Hodge numbers and
special K\"ahler geometry on the complex structure moduli space and
are associated with the same $N=2$ gauge linear sigma model. We give
the explanation of this interesting coincidence using the Batyrev's
correspondence between Calabi-Yau manifolds and the reflexive
polyhedra. <br>
