Classification of Joint Numerical Ranges of Three Hermitian Matrices of Size Three
The joint numerical range of three hermitian matrices of order three is a convex and compact subset W ⊂ R which is an image of the unit sphere S ⊂ C under the hermitian form defined by the three matrices. We label classes of the analyzed set W by pairs of numbers counting the exposed faces of dimension one and two. Generically, W belongs to the class of ovals. Assuming dim(W ) = 3, the faces of...

15 صفحه اولEla Hermitian Octonion Matrices and Numerical Ranges
Notions of numerical ranges and joint numerical ranges of octonion matrices are introduced. Various properties of hermitian octonion matrices related to eigenvalues and convex cones, such as the convex cone of positive semidefinite matrices, are described. As an application, convexity of joint numerical ranges of 2×2 hermitian matrices is characterized. Another application involves existence of...

متن کاملa comparative study of the theme of "marriage" in three victorian novelists: charles dickens, george eliot and thomas hardy
این تحقیق کوشیده است با انتخاب پنج رمان از میان آثار برگزیده، «چارلز دیکنز»، «جورج الیوت» و «توماس هاردی » و با رویکردی تطبیقی به بررسی درونمایه ی «ازدواج» در آثار این سه رمان نویس بزرگ دوره ی ویکتوریا بپردازد. فرضیه ی اولیه ی تحقیق این بوده است که چارلز دیکنز (1870- 1812) با زبانی شوخ و گزنده، جورج الیوت(1880- 1819) با نگاهی آموزشی–اندرزگونه و توماس هاردی(1928- 1840) با رویکردی تلخ وانتقادی به...
