Abstract

In this research, we give the upper and lower bounds for the spectral norm of geometric and symmetric geometric circulant matrices with the exponential function, and we obtain 1-norm and ∞-norm for them. Furthermore, some numerical examples for demonstrating the validity of the hypotheses of our results are given.
