We introduce concepts of diagonalquasi-convexity and quasi-concavity in hyperconvex metric spaces.
我们介绍了超凸度量空间中对角拟凸和拟凹的概念。

We introduced the concept of block directed edge cover diagonalquasi dominant matrix, obtained a new nonsingularity criteria for matrices and distribution theorem on eigenvalues of matrix.
引进了拟块有向边覆盖对角占优矩阵概念，给出了新的矩阵非奇异判定定理和特征值分布定理。
