In this paper,we study large m asymptotics of the l1 minimal m-partition problem for the Dirichlet eigenvalue.For any smooth domain Ω (C) Rn such that |Ω| =1,we prove that the limit limm→∞ l1m(Ω) =c0 exists,and the constant c0 is independent of the shape of Ω.Here,l1m(Ω) denotes the minimal value of the normalized sum of the first Laplacian eigenvalues for any m-partition of Ω.
