Keywords: | Indefinite numerical range; Indefinite inner product space; Plane algebraic curve; Flat portion | Issue Date: | 2008 | Citation: | Linear Algebra and its Applications. 428:11-12 (2008) 2863-2879 | Abstract: | We focus on complex 3×3 matrices whose indefinite numerical ranges have a flat portion on the boundary. The results here obtained are parallel to those of Keeler, Rodman and Spitkovsky for the classical numerical range. | URI: | https://hdl.handle.net/10316/4584 | DOI: | 10.1016/j.laa.2008.01.017 | Rights: | openAccess |
