چکیده
|
For a positive integer m, a subset of divisors of m is called a divisor topology on m if it contains and m and it is closed under taking and . if m p1...pn is a square free positive integer, then a divisor topology m corresponds to a topology on the set n , ,...,n. giving some facts about divisor topologies, we give a recursive formula for the number of divisor topologies on a positive integer.
