RESEARCHES OF IMPROPER POSITIVE DEFINITE MATRIX

Sun Jiandong(Tank Aebdemy Teaching Research Section of Matematies)  
An improper positive definite matrix set P[I] is definite matrix set P[S+], which is wider than P[I], is defined in paper [2]. And in this paper, certain properties of the matrix in P[I] are expanded into P(S+), so that the results of P(S+) are enriched.
