Abstract
In this paper, we find the number of representations of certain quadratic forms in 20 and 24 variables. We get this as an application of the evaluation of certain triple convolution sums of the divisor functions. Further, by comparing our formulas with that of Lomadze, we get expressions of certain cusp forms in terms of some finite sums involving the solution set of the quadratic form representation.
