报告摘要：

The geometric compactifications of moduli spaces ofhigher dimension varieties were studied by Kollar, Shepherd-Barron and Alexeevaround 30 years ago. We will introduce some fundamental results oncompactification of moduli of hyperplane arrangements by matroid theory. Thenwe will give some generalizations of this tool and apply it on a special familyof CY 3-folds.
