Introductory to Functional Analysis

  1. Oct 13, 2011 #1
    Folks,

    I am starting a module in functional analysis undergrad level. I have been suggested introductory functional analysis by Kreyszig, but in instead of buying another expensive book is there a good online source like a pdf on in this topic that I could avail of?

    Any help will be appreciated.

    Kind regards
    Eddie

    Kreyszig (700 pages from 1978) is VERY good and provides you with a lot of information. If you're really interested in this topic of maths, make an effort & get it.

    Thank you guys. I got my hands on Kreyszig.

    What I am missing now some useful link detailing

    1) all the notations used in Functional analysis like the symbol for 'subset', 'is an element if', 'for all' etc etc. I see kreyszig has some notation but its not completely definitive?

    2) A link to the equivalent Latex notation so i can write on this forum.

    Thanks

    1) I don't understand. Check his page 609 where he starts an appendix on set theory and has all the notations listed. What do you mean definitive ? Are there any inconsistencies ?

    2) You can type on this forum using TEX/LATEX code. Search this forum or the internet for tutorials.

    EDIT: Here's a free tutorial I found in my computer.

    & the kreyszig book is great. it does basic functional analysis & keeps the measure & topology to a minimum. the only topology that I remember off the top of my head is sequential compactness.
