I'm a student (I've been studying mathematics 4 years at the university) and I like functional analysis and topology, but I only studied 6 credits of functional analysis and 7 in topology (the basics). What I am looking for is good books that I could understand to go deeper in this areas, what do you recommend? (I can read in Spanish, English, French and German)



A good book of functional analysis
I am an algebraist and not an analyst, however my favourite book on this area is "Walter Rudin: Functional Analysis".
