Query: Some studies on Loewy lengths of centers of p-blocks   In this paper, we investigate some relations between the Loewy lengths of the
centers of blocks of group algebras and its defect groups. In particular, we
give a new upper bound of the Loewy length and determine the structure of
blocks with large Loewy length.
