is an antieigenvector of a
strictly accretive operator A is obtained. The structure of antieigenvectors of selfadjoint and certain
class of normal operators is also found in terms of eigenvectors. The Kantorovich inequality for
selfadjoint operators and the Davis's inequality for normal operators are then easily deduced. A
sort of uniqueness is also established for the values of
Re(Af,f) and ‖Af‖ if the first antieigenvalue, which is equal to min Re(Af,f)/(‖Af‖‖f‖) is attained at the unit vector f.">

f是严格的antieigenvector粘连的运营商
一个是获得。antieigenvectors自伴和某些类的结构正常的运营商也发现的特征向量。Kantorovich不等式为自伴算子和戴维斯的不平等然后正常算子容易推导出。一种独特性也建立了的值
