We are interested in the polar factorization of a function f deÿned in an open bounded set ⊆ R N . It is well known that there exists a measure preserving map such that f=f \* • where f \* is the decreasing rearrangement of f. We prove that, under suitable assumptions, besides the classical polar fa
