Their notion of degree, which we call the EKL-degree, can be thought of as a refinement of the usual notion of local degree in algebraic geometry that works over non-algebraically closed base fields, taking values in the Grothendieck-Witt ring. In this note, we compute the EKL-degree at the origin of certain finite covers $f\\colon \\mathbb{A}^n\\to \\mathbb{A}^n$ induced by quotients under actions of Weyl groups.
