A Study on the Number of Representations of an Integer into Certain Quadratic Forms

Kritika Kashyap

Let $a_k(n)$ denotes the number of representations of a non-negative integer $n$ as sum of $k$ quadratic forms of the type $x^2+xy+y^2$ and $a_{{\lambda }_1,{\lambda }_2,{\lambda }_3\dots {\lambda }_k}(n)$ denotes the…
