Abstract

We prove on some nested fractals scale invariant LpL^p-Poincar\'e inequalities on metric balls in the range 1p21 \le p \le 2. Our proof is based on the development of the local LpL^p-theory of Korevaar-Schoen-Sobolev spaces on fractals using heat kernel methods. Applications to scale invariant Sobolev inequalities and to the study of maximal functions and Haj\l{}asz-Sobolev spaces on fractals are given. Results are illustrated and further developed in the case of the Vicsek set.
