复正定阵的Kronecker乘积与Hadamard乘积

Krotlecker product and Hadamard product of the complex positive matrices

本文给出复正定阵的Kronecker乘积与Haeamard乘积仍为复正定阵的条件。这是Schur关于实正定阵的Hadamard乘积的著名结果及华罗庚定理在复正定阵上的推广。

In this paper , we give the necessary and sufficient condition of the xomplex positive olifinite matricesfor A×B and A · B.
