The Numerical Radius Unit Ball for 2×2 Matrices

碩士 === 東海大學 === 數學系 === 93 === This thesis is to explore the numerical radius unit ball for 2×2 matrix. The computation of the radius for the 2×2 matrix are studied first. By using the unitary matrix, any 2×2 matrix can be transferred into the upper-triangular form. For the numerical radius unit bal...
