I need a book covering $L^p$ theory (is it?) on PDE. Stuff should include: De Giorgi-Nash-Moser’s iteration, Harnack inequalities and Schauder estimates on elliptic/parabolic homogeneous/heterogeneous equations, together with their divergence forms.
I've found Jürgen Jost's Partial Differential Equations, whose second half provides more or less I need. Can you recommend some other books providing full details on those topics for me? Thank you~
