Let A(n) be the (1, n) − th Fourier coefficients of SL(3, Z) Hecke-Maass cusp form i.e. Λ(1, n) or the triple divisor function d 3 (n), which is the number of solutions of the equation r 1 r 2 r 3 = n with r 1 , r 2 , r 3 ∈ Z + . We establish estimates forwhere Q(x, y) ∈ Z[x, y] is a symmetric positive definite quadratic form.
