abstract = { In  this  paper,  we  improve  the  disc  separation  of  the  Schur  complement  of  strictly  diagonally 
dominant matrices presented in Liu [SIAM. J. Matrix Anal. Appl., 27 (2005): 665-674]. As applications, we 
present  some  new  bounds  for  determinants  of  original  matrices  and  estimations  for  eigenvalues  of  Schur 
complement. By theoretical analysis, we improve the bounds of determinants established in Huang [Comput. 
Math. Appl., 50 (2005): 1677-1684].
