Title: Formal groups of low dimensional Calabi-Yau varieties

Abstract: Calabi-Yau varieties are associated with formal groups of dimension one. When they are defined over an algebraically closed field of positive characteristic, the formal groups are classified by the height. Using weighted Delsarte varieties of low dimensions (say, $2$, $3$ or $4$), we describe how to compute the height of their formal groups and show various numerical data for them.
