In
Mathematica, DivisorSigma[k,n] calculates the sum of the
powers of the divisors of
. For example, you can use
DivisorSigma[0,n] in order to determine the number of divisors of the integer
and
DivisorSigma[1,n] to determine the sum of these divisors. This Demonstration allows you to visualize the results of applying
DivisorSigma to various ranges of integers.
When Gaussian integers are selected, the Demonstration returns a plot of the absolute values of
DivisorSigma, since the result may be complex.
