Analysis of Partial Differential Equations in Memory of David R. Adams
Operators of the form $Lu=\nabla\cdot (A\nabla u)$, that is, second order linear differential operators in divergence form, are by now very well understood. Two important generalizations are higher order operators $Lu=\nabla^m\cdot (A\nabla^m u)$, for $m\geq 2$ an integer, and operators with lower order terms $Lu=\nabla\cdot (A\nabla u) + \nabla\cdot (Bu) + C\cdot \nabla u+Du.$ In this talk we discuss our attempt to combine the two generalizations and study higher order operators with lower order terms.
