We define Stummel-Kato type classes in a quasimetric homogeneous setting using sum operators introduced in [13] by Franchi, Perez and Wheeden. Then we prove a Harnack inequality for positive solutions of some linear subelliptic equations.
Keywords: Harnack inequality., Stummel-Kato type classes, Fefferman-Phong inequality.
