Given a binary quadratic polynomial \(f(x_1,x_2)=\alpha x_1^2+\beta x_1x_2+\gamma x_2^2\in \mathbb {Z}[x_1,x_2]\), for every \(c\in \mathbb Z\) and \(n\ge 2\), we study the number of solutions \(\mathrm {N}_J(f;c,n)\) of the congruence equation \(f(x_1,x_2)\equiv c\bmod {n}\) in \((\mathbb {Z}/n\mathbb {Z})^2\) such that \(x_i\in (\mathbb {Z}/n\mathbb {Z})^\times \) for \(i\in J\subseteq \{1,2\}\).

关于二元二次形式模

给定一个二进制二次多项式\(f(x_1,x_2)= \ alpha x_1 ^ 2 + \ beta x_1x_2 + \ gamma x_2 ^ 2 \ in \ mathbb {Z} [x_1,x_2] \),对于每个\(c \ in \ mathbb Z \)\(n \ ge 2 \),我们研究了全等式\(f(x_1,x_2)的解数\(\ mathrm {N} _J(f; c,n)\ ) \当量ç\ BMOD {N} \)\((\ mathbb {Z} / N \ mathbb {Z})^ 2 \),使得\(X_I \在(\ mathbb {Z} / N \ mathbb {Z })^ \ times \)表示\(i \ in J \ subseteq \ {1,2 \} \)
