how can I understand the difference between algebra, sigma algebra and topology
If I take the set A that contains a,b,c,d,e,f
the set C that contains A,phi,{a},{b,c,d,e,f}
then C is algebra on A
and C is sigma algebra on A
and (A,C) is topological space
is that true?
what is the difference ?
give me example like the obove to see the difference between them?
