Introductory to Functional Analysis

[bugatti79]

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

Here are some free resources: http://hbpms.blogspot.com/2008/05/stage-4-analysis.html

But remember: if you want quality, then you'll have to pay for it. And Kreyszig is quality. It's one of the better math books out there.

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.

ok, thanks dextercioby although I am waiting for that attachment to be approved that last few days :-)

& 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.
