Odd-order groups with small average number of zeros of characters.

AbstractWe define, and denote by anz(G), the average number of zeros of characters of a finite group <italic>G</italic> as the number of zeros in the character table of <italic>G</italic> dividing the number of irreducible characters of <italic>G</italic>. In this paper, we classify odd-order nonabelian groups <italic>G</italic> with anz(G)≤2. [ABSTRACT FROM AUTHOR]
