Spanning sets for Möbius vertex algebras satisfying arbitrary difference conditions

Spanning sets for vertex operator algebras satisfying difference-zero and difference-one conditions have been extensively studied in the recent years. In this paper, we extend these results. More specifically, we show that for a suitably chosen generating set, any View the MathML source-graded Möbius vertex algebra is spanned by monomials satisfying a difference-N ordering condition.
