We study second-order differential operators A with lower-order coefficients in some L q L . We prove the generation of positive, quasi-contractive C semiq ฯฑ 0 ลฝ . groups on L for all p g 1, ฯฑ . If the second-order coefficients are in some p L q L , we get upper pseudo-Gaussian bounds of the heat ke
