in a bounded domain \(\Omega \subset \mathbb{R}^{n}\) (\(n\ge 2\)) with smooth boundary \(\partial \Omega \). Under the condition that \(\alpha >\frac{2n-mn-2}{2(n-1)}\), \(m\geq 1\), and \(\beta \leq \frac{m+2}{2}\), it is shown that the problem possesses a unique global bounded classical solution. Moreover, it is obtained that the corresponding solution exponentially converge to a constant stationary solution when the initial data \(u_{0}\) is sufficiently small.
