dual intersection complex, a topological space that encodes the combinatoric of
the central fiber and reflects the geometry of the generic fiber. In this talk
I will show how the techniques of Berkovich geometry give an insight in the
study of the dual complexes. In this way, we are able to determine the
homeomorphism type of the dual complex of some degenerations of hyper-Kähler
varieties. The results are in accordance with the predictions of mirror symmetry,
and the recent work about the rational homology of dual complexes of
degenerations of hyper-Kähler varieties, due to Kollár, Laza, Saccà and Voisin.
