ABSTRACT
In this paper we confirm three conjectures of Z.-W. Sun on determinants. We first show that any odd integer n>3 divides the determinant where d is any integer and is the Jacobi symbol. Then we prove some divisibility results concerning and , where and n>2 are integers. Finally, for any odd prime p and integers c and d with , we determine completely the Legendre symbol , where .

关于与二次残基有关的行列式的三个猜想的证明
摘要
在本文中,我们确定Z.-W的三个猜想。太阳决定因素。我们首先证明n > 3的任何奇数整数都会除行列式其中d是任何整数,是雅可比符号。然后我们证明一些关于 和 ,在哪里 和Ñ > 2是整数。最后,对于任何奇素数p和整数ç和d与,我们完全确定了Legendre符号 ,在哪里 。
