Abstract
We apply the techniques developed in our previous work with Leung to study smoothings of a pair , where is a bounded perfect complex of locally free sheaves over a degenerate Calabi-Yau variety . In particular, if is a projective Calabi-Yau variety admitting the structure of a toroidal crossing space and with the higher tangent sheaf globally generated, and is a locally free sheaf over , then we prove, using the recent results of Felten-Filip-Ruddat, that the pair is formally smoothable when and .
