AB - The generating functions of divisor functions are quasimodular forms of weight 2 and their products belong to a space of quasimodular forms of higher weight. In this article, we evaluate the convolution sums ∑al+bm=nlσ(l)σ(m) \[\begin{array}{} \displaystyle \sum \limits _{al+bm=n}\,l\sigma (l)\sigma (m) \end{array} \]
for all positive integers a, b and n with ab ≤ 9 and gcd(a, b) = 1.
