Query: Squarefree vertex cover algebras   In this paper we introduce squarefree vertex cover algebras. We study the
question when these algebras coincide with the ordinary vertex cover algebras
and when these algebras are standard graded. In this context we exhibit a
duality theorem for squarefree vertex cover algebras.
