摘要: 确定出13个元素的有限域F13上A2型Chevalley群G(1)=SL(3,13)的Cartan不变量矩阵C=(c(1)λμ)λ,μ∈X1(T),利用MATLAB软件计算C的行列式的值是1318,符合Brauer的结论.Abstract: The Cartan invariant matrix C=(c(1)λμ)λ,μ∈X1(T) for Chevalley group G(1)=SL(3,13) of type A2 over the finite field F13 with 13 elements was determined, and det C=1318was given by MATLAB soft.
