Role of numerical range on some operator equations in Hilbert spaces
Author(s): Emmanuel Kipruto, Linety Muhati and Collins Meli
Abstract:
In operator theory equations occur in various situations. Some authors who have used the numerical range in solutions of such equations have mainly put some conditions on the closure of the numerical range rather than its interior. In this paper our task is to try and relax the conditions on the closure to mere interior of the numerical range.
