Systems of Hermitian Quadratic Forms
In this paper, we give some conditions to judge when a system of Hermitian quadratic forms has a real linear combination which is positive definite or positive semi-definite. We also study some related geometric and topological properties of the moduli space.

Keywords:hermitian quadratic form, positive definite, positive semi-definite
