Quadric Completion of Operator Partial MatricesII
Jian Cui · Gongcheng shuxue xuebao · 2001
For any given quadric polynomial p(t),the necessary and sufficient conditions are obtained for operator partial matrices of the formA C? B to be completed to an operator T such that p(T)=0.In many cases, all such possible completions, if any exist, are presented parametrically.
