Abstract
In this paper we study a spectral characterization of the Taylor-Browder spectrum for a double commuting n − tuple of totally θ −operators, and study relation between the Taylor- Weyl spectrum, Taylar- Browder spectrum, joint-Weyl spectrum, and joint- Browder spectrum for commuting n − tuple of totally θ −operators. Also we study a spectral characterization of the Taylor-Browder spectrum for a doubly commuting n − tuple of posinormal operators.
