1) quadratic integer square
二次整数方
1.
This paper also gives the definition of quadratic integer squares alone with the product between them and replace of proving the existence of pandiagonal magic squares of orders mn by proving the existence of pandiagonal magic squares of orders m and n respectively.
本文给出了二次整数方及其乘积的定义 ,化mn阶全对角线幻方的存在性为m阶和n阶全对角线幻方的存在性 。
2) product of quadratic integer square
二次整数方的乘积
1.
Again, using the product of quadratic integer squares, constructs the family of pandiagonal magic squares of all orders n≠2,3,4t+2.
再用二次整数方的乘积 ,给出了所有n≠ 2 ,3 ,4t+2 ,9t± 3阶的一族全对角线幻方 。
3) mixed integer quadratic programming approach
混合整数二次规划方法
4) number square of the second power
二次数方
6) intergral coefficient quadratic factorization
二次整系数因式
1.
Using Gel found-Baker method,this paper proves that if x~n-bx-a has intergral coefficient quadratic factorizations,then n< max(87｜b｜,512 870),besides cases n≡2(mod3),b=-1,a=-1,and n≡2(mod6),b=1,a=-1.
设n≥5,a,b≠0,n∈N,a,b∈Z,利用Gel'found Baker方法证明:若多项式xn-bx-a有二次整系数因式,则除了n≡2(mod6)且b=1,a=-1,与n≡2(mod3)且b=-1,a=-1这些明显情形外,必有n
