Abstract: |
This paper focuses on the estimation of the sub-eigenvalue.Some specific problems are discussed,such as the modulus of the sub-eigenvalue,the upper bound of the real part and imaginary part of the sub-eigenvalue,the upper bound of the modulus of the produ |
Key words: sub-eigenvalue,modulus,conjugate sub-transpose matrix,real sub-symmetric matrix,sub-Hermitian matrix,sub-normal matrix,upper bound. |
