Abstract
In this article, a series of new inequalities involving the -numerical radius for tridiagonal, and anti-tridiagonal operator matrices has been established. These inequalities serve to establish both lower and upper bounds for the -numerical radius of operator matrices. Additionally, we developed -numerical radius inequalities for circulant, skew circulant, imaginary circulant, imaginary skew circulant operator matrices. Important examples have been used to illustrate the developed inequalities. In this regard, analytical expressions and a numerical algorithm have also been employed to obtain the -numerical radii. We also provide a concluding section, which may lead to several new problems in this area.
