why algebra , analysis and topology are considered as very important topics in graduate programmes coursework ?
Note : Im still pursuing my master and im going to do phd in future
I see many U.S and other country university this three subject algebra , analysis and topology are always included and make as a compuslory subject in course work
I don't understant why this three topics are make compulsory ?
why not only analysis ? or why not only Algebra ? why not only topology?
