Hello
I am trying to learn more about Fréchet spaces (in order to study the theory of distributions) and was wondering what people thought was the best resource.
Thank you very much.
I don't know much about distributions but if you're entering this area with such a motivation, maybe you could use Horvath's book "Topological vector spaces and distributions". The first part is a fine introduction to locally convex space theory in itself, and the presentation of this (rather standard) material should be convenient for anybody interested on the final chapter -- distributions.
By the way, a linear topology on a vector space which is defined using a family of seminorms is in general a locally convex topology, not necessarily metrizable (Fréchet spaces are metrizable and complete locally convex spaces).
I just had a look at
Topological Vector Spaces, Distributions and Kernels
by Francois Treves. It is divided into three parts:
I Topological Vector Spaces. Spaces of Funtions
II Duality, Spaces of Distributions
III Tensor Products. Kernels
From the first sight, this looks like a good place to start if you are already familiar with functional analysis on Banach and Hilbert spaces.
