In this paper we explore a research problem of Greene: to find inequalities for the Miibius function which become equalities in the presence of modularity. We replace these inequalities with identities and give combinatorial interpretations for the difference.
Let K be a finite field of characteristic p > 2, and let M 2 Γ°KΓ be the matrix algebra of order two over K. We describe up to a graded isomorphism the 2-gradings of M 2 Γ°KΓ. It turns out that there are only two nonisomorphic nontrivial such gradings. Furthermore, we exhibit finite bases of the grade
