readable with plenty of problems to work with.
It's juicy with applications, though.
Great if you're transitioning from ODE's.
I was surprised when I pulled this out the box
when it arrived, but the Handbook of Mathematics
takes the cake for the thickness.
Hörmander's linear PDE's series from
>>13461810 looks like some good shit if you'reanalysis oriented.
