Streszczenie
We study certain contact metrics satisfying the Miao–Tam critical condition. First, we prove that a complete $K$-contact metric satisfying the Miao–Tam critical condition is isometric to the unit sphere $S^{2n+1}$. Next, we study $(\kappa , \mu )$-contact metrics satisfying the Miao–Tam critical condition.
