摘要：
Let N (a(1), ... , a(4); n) denote the number of representations of an integer n by the form a(1)(x(1)(2) + x(1)x(2) + x(2)(2))+ a(2)(x(3)(2) + x(3)x(4) + x(4)(2))+ a(3)(x(5)(2) + x(5)x(6) + x(6)(2))+ a(4)(x(7)(2) + x(7)x(8) + x(8)(2)). In this paper we derive formulae for N(1, 1, 1, 2; n) and N(1, 2, 2, 2; n). These formulae are given in terms of sigma(3)(n).
