A structure theorem for elliptic and parabolic operators with applications to homogenization of operators of Kolmogorov type

M. Litsgård, K. Nyström

We consider the operators \[ \nabla_X\cdot(A(X)\nabla_X),\ \nabla_X\cdot(A(X)\nabla_X)-\partial_t,\ \nabla_X\cdot(A(X)\nabla_X)+X\cdot\nabla_Y-\partial_t, \] where , $(X,t)…
