CALABI--YAU THREEFOLDS FROM PAIRS OF FANO THREEFOLDS WITH PICARD NUMBER ONE

초록

We construct Calabi–Yau threefolds from pairs of Fano threefolds with Picard number one by smoothing method. It turns out that all those Calabi–Yau threefolds are of Picard number one and appears as an anticanonical section of Fano varieties (possibly singular) of dimension four.
