Bi-Lipschitz multiplicity conjecture for complex analytic germs

Let XCnX\subset \mathbb{C}^n and YCmY\subset \mathbb{C}^m be complex analytic sets with dimX=dimY=d\dim X=\dim Y=d. Their germs at zero are bi-Lipschitz homeomorphic if there is a bi-Lipschitz homeomorphism between them. Bi-Lipschitz multiplicity conjecture. If the germs of XX and YY at zero are bi-Lipschitz homeomorphic, then their multiplicities satisfy

m(X,0)=m(Y,0).m(X,0)=m(Y,0).

This conjecture concerns whether multiplicity is preserved by bi-Lipschitz equivalence of complex analytic germs. The source states that it was proposed in earlier work and that Zariski's broader multiplicity conjecture remains open.
