Distribution theory book
Two books I have been reading are Strichartz's A Guide to Distribution Theory and Fourier Transforms and PartII of Rudin's Functional Analysis . Both are good books.
However, the problem I am facing is that Rudin is sometimes too compact for me. It is like the author is trying to hide as much as insight and motivation as possible, which is not a very appropriate approach to distributions since they are actually a very 'practical' tool whose value lies in its usefulness. On the other extreme, Strichartz is too intuitive. For instance he does not give a clear examination about the topology of test functions, let alone the space of distributions ('At any rate, all functionals you will encounter are continuous' p4).
I found it difficult to combine these two books. It would be helpful if there is some good reference that lies between these two extremes.
Thanks!
