Keywords: | Numerical range; Generalized numerical range; Indefi nite inner product space | Issue Date: | 2003 | Publisher: | Centro de Matemática da Universidade de Coimbra | Citation: | Pré-Publicações DMUC. 03-07 (2003) | Abstract: | In this paper, numerical ranges associated to operators on an inde nite inner product space are investigated. Boundary generating curves, corners, shapes and computer generations of these sets are studied. In particular, the Murnaghan- Kippenhahn theorem for the classical numerical range is generalized. | URI: | https://hdl.handle.net/10316/11439 | Rights: | openAccess |
