Research output: Contribution to journalArticlepeer-review


Let $$\mathbb {G}$$G be a Carnot group with homogeneous dimension $$Q \ge 3$$Q≥3 and let $${\mathcal L}$$L be a sub-Laplacian on $$\mathbb {G}$$G. We prove that the critical dimension for removable sets of Lipschitz $${\mathcal L}$$L-harmonic functions is $$(Q-1)$$(Q-1). Moreover we construct self-similar sets with positive and finite $$\mathcal {H}^{Q-1}$$HQ-1 measure which are removable.
