摘要
In this paper it is proved that Cameron-Liebler line classes with parameter x do not exist when 2 < x <= q. We also give a geometrical-combinatorial proof of the equivalent properties that can be used to define Cameron-Liebler line classes. Finally, we use the same technique as in this proof to prove a result on partial m-covers of the classical parabolic generalized quadrangle.
