One usually specifies "Hodge dual", or "Hodge star operator", to avoid confusion. blackland transitional housing austinNettetIn case n = 4, the Hodge dual acts as an endomorphism of the second exterior power (i.e. it maps two-forms to two-forms, since 4 − 2 = 2). It is an involution, so it splits it into self-dual and anti-self-dual subspaces, on which it acts respectively as +1 and −1. blackland water well serviceNettetHodge dual of an array that is antisymmetric only in some slots: Specify in which slots to dualize: Hodge dual in some slots only: HodgeDual of a symbolic array: Properties when using the single-argument form or a redundant second argument: Using the two-argument from to dualize in a different dimension: blackland wiltshire
