英文摘要:In this talk, we revisit the weighted $L^2$-theory for the Dirac operator established by professor Ji Qingchun and Zhu Ke. We then demonstrate that the classical $L^2$-existence theorem—valid for domains in $\mathbb{R}^2$ under a subharmonic weight condition—fails in higher dimensions. Finally, we present an improvement upon the results of Ji and Zhu by deriving a refined a priori estimate, thereby overcoming the restrictive structural conditions previously imposed on the weight function.
