Some useful operators on differential forms on Galilean and Carrollian spacetimes (Q6110579)

This paper deals with some new operators and differential forms on Galilean and Carrollian spacetimes, where the theory of Hodge star operators is not well-established. The author shows that a Hodge star operator can be defined as an intertwining operator between representations on forms. As the author claims, this operator is a potential new tool for physicists working with Galilean and Carrollian spacetimes.
