So I asked this question about Rigged Hilbert Space
https://www.physicsforums.com/showthread.php?t=435123
And one of the problem I have understand Rigged Hilbert Space is that it involves taking the dual of a particular dense subspace of Hilbert Space and I of course have no clue what the dual or http://en.wikipedia.org/wiki/Dual_space" is. Even though I have a very amateur understanding abstract vector space, I get really confused about what exactly Dual Space is and what articles like wikipedia mean when they talk about concepts like bilinear mapping or a natural isomorphism in reference to dual space.
So, could anyone provide a general introduction to what Dual Spaces are and how they work?
