The Boundary of Numerical Ranges
碩士 === 東吳大學 === 數學系 === 100 === In this paper we study the boundary of the numerical ranges. Let S = {x : x^*x = 1, x E C^n}. The numerical range of an n × n complex matrix A is defined to be the set W(A) = {x^*Ax : x 2 S}. We list some fundamental properties in section 1. In section 2, we discuss t...
