论文摘要
对于每个整数$ x $，$ x $ th的广义五角形号码用$ p_5（x）=（3x^2-x）/2 $表示。给定奇数的正整数$ a，b，c $和非阴性整数$ r，s $，我们采用三元二次形式的理论来确定何时sum $ $ ap_5（x）+2^rbp_5（y）+2^scp_5（z）$代表了几乎一定的积极整数。
For each integer $x$, the $x$-th generalized pentagonal number is denoted by $P_5(x)=(3x^2-x)/2$. Given odd positive integers $a,b,c$ and non-negative integers $r,s$, we employ the theory of ternary quadratic forms to determine when the sum $aP_5(x)+2^rbP_5(y)+2^scP_5(z)$ represents all but finitely many positive integers.
