I'm looking to take an independent study on Partial Differential Equations. I will hopefully be keeping Walter Strauss' Partial Differential Equations: An Introduction and Lawrence Evans' Partial Differential Equations as references.
Can someone recommend a textbook that covers the pre-requisite material from measure theory, functional analysis (and maybe even vector calculus) that is used in PDE's. I know a bit of measure theory, and I'll be taking a class on it as well. I haven't studied functional analysis.
It'd be great if someone could recommend a textbook that covers the said pre-requisite material required for PDE's at the level appropriate for the aforementioned books.
