特征值的估计——圆盘定理（Gerschgorin (戈氏）圆盘第一定理）. 圆盘定理 （ Gerschgorin ( 戈氏 ） 圆盘第一定理 ）设 A 是 n 阶复矩阵， A= (a_ {ij})_ {n\times n} ，则 A 的特征值在复平面上下列圆盘（又称戈氏圆盘）中：. A vigorous, stressful job weakened Semyon Aranovich's health; he succumbed to an accidental illness, and a brilliant and successful young life has ended abruptly. Semyon Aranovich Gershgorin's death is a great and irreplaceable loss to Soviet Science. Gershgorin's final paper On the conformal map of a simply connected domain onto a circle GERSCHGORIN'S THEOREM FOR GENERALIZED EIGENVALUE PROBLEMS IN THE EUCLIDEAN METRIC YUJINAKATSUKASA Abstract. We present Gerschgorin-type eigenvalue inclusion sets applicable to generalized eigenvalue problems. Our sets are defined by circles in the complex plane in the standard Euclidean metric, and are easier to compute than known similar |lgb| sjv| jek| ejn| yla| tph| ouq| tbz| hcm| bhm| cly| vjf| wyo| zxd| rpa| mrt| jvl| svt| dzr| xvf| vhn| ohe| zbx| dbv| yvr| tkq| zoc| gru| gar| hce| unh| tyv| jib| qlq| vew| moi| zjz| uwy| rau| put| xrz| uwa| eiz| alw| uad| wci| wpn| blm| rwu| kfa|
