在国内，万哲先与他的学生和合作者们利用线性空间的办法，讨论了在有限域上的典型群作用下，由各个轨道或相同维数和秩的子空间生成的几何格。
, his students and cooperators construct geometric lattice by means of linear spaces , and discuss the geometric lattice that generated by various orbits or subspaces with the same dimension or rank under the action of classical groups over finite field .
