本文给出了一个新的无穷族Cameron-Liebler线类的代数构造,其中参数x= q2 − 12,q ≠ 5或9(mod 12),推广了Rodgers在[26]中通过计算机搜索得到的例子.在q为3的偶次幂的情形下,我们构造了AG(2,q)中的第一个仿射两交集无限族,它与我们的Cameron-Liebler线类密切相关.
In this paper, we give an algebraic construction of a new infinite family of Cameron–Liebler line classes with parameter x= q 2− 1 2 for q≡ 5 or 9 (mod 12), which generalizes the examples found by Rodgers in [26] through a computer search. Furthermore, in the case where q is an even power of 3, we construct the first infinite family of affine two-intersection sets in AG (2, q), which is closely related to our Cameron–Liebler line classes.
