Abstract: |
Let  denote the product of all exponential divisors of  . An integer is called multiplicatively  -perfect if  and multiplicatively -superperfect if  . In this note, we give an alternative proof for characterization of multiplicatively -perfect and multiplicatively -superperfect numbers.
