报告摘要：

In this talk, we will explore the blowup properties of a sequence of $\alpha_k$-harmonic maps, denoted as $u_k$, from a closed surface $\Sigma$ to a closed manifold $(N,h)$. We will 

1. prove that the neck region is composed of geodesics;

2. establishing a weak energy identity;

3. verifying an energy identity under the conditions of $Ric_h > 0$ and the boundedness of the index of $E_{\alpha_k}(u_k)$.
