    　View Summary

    <p>We establish the existence of a scaling limit of discrete -energies on the graphs approximating a generalized Sierpiński carpet for , where is the Ahlfors regular conformal dimension of the underlying generalized Sierpiński carpet. Furthermore, the function space defined as the collection of functions with finite -energies is shown to be a reflexive and separable Banach space that is dense in the set of continuous functions with respect to the supremum norm. In particular, recovers the canonical regular Dirichlet form constructed by Barlow and Bass [Ann. Inst. H. Poincaré Probab. Statist. 25 (1989), pp. 225–257] or Kusuoka and Zhou [Probab. Theory Related Fields 93 (1992), pp. 169–196]. We also provide -energy measures associated with the constructed -energy and investigate its basic properties like self-similarity and chain rule.</p>
