Abstract

In this paper, we define h-Shuhan matrix, which is the generalization of the generalized Cartan matrix, and find the h-Shuhan matrices for all positive semi-definite ( or generalized positive semi-definite, virtual positive semi-definite) with h<2h<2. Furthermore, we know that the largest eigenvalue of the matrix B^nh\hat{B}_{n}^{h} increases with nn, but it is always less than hh plus a constant ϵ2.04998\epsilon\approx2.04998.
