In the present paper, we construct geometric lattice with idempotentmatrix.
本文就想利用特殊矩阵来构造几何格。

Let R be an abelian ring ( all idempotents of R lie in the center of R), and A be an idempotentmatrix over R.
设R是一阿贝尔环(R的所有幂等元都在中心里),A是R上的一幂等阵。

Nine equivalent conditions of real idempotentmatrix are given and proved, and one equivalent condition of real symmetric idempotentmatrix is also given in this paper.
