Quasisymmetric minimality on packing dimension for Moran sets

In this paper, we prove that if sup k n k < ∞ and c k , 1 = c k , 2 = ⋯ = c k , n k for any k , or if c ∗ = inf k , j c k , j > 0 , the Moran set E ∈ M ( I , { n k } , { c k , j } ) on the line with packing dimension 1 are quasisymmetrically packing-minimal.
