Nanofiltration (NF) is a promising technology to remove the perfluoroalkyl acids, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) from water; however, little information is available as to how the natural water matrices impact PFOA and PFOS rejection when using NF.

Well-posed Schrödinger equation
hi,
i need to find non trivial conditions, for which the following system is well posed.
and then prove it is well posed.

u_{t}=\imath [A_{1}u_{xx} + A_{2}u_{yy}] \ + \ B_{1}u_{x}+B_{2}u_{y} \ +\ Cu \ +\ F \
