==Definition==

Suppose <math>n</math> and <math>k</math> are [[natural number]]s. The '''sum of squares function''' <math>r_k(n)</math> is defined as the number of ways <math>n</math> can be expressed as a sum of <math>k</math> squares, counting different signs and different permutations as different ways.
