我们用全息术研究了由(p，q)5膜网设计的5DSCFT中的共维2表面缺陷。三维缺陷是通过在膜腹板上终止的D3膜实现的。我们确定了IIB型ADS6溶液中缺陷的全息表示为探针D3膜，并研究了分别保持一半和四分之一超对称性的共形和非共形缺陷。对于包括T-N理论在内的5维SCFT样品，我们给出了共形和非共形缺陷的显式解。对于共形缺陷，我们得到了它们对S 5的自由能的贡献。
We use holography to study codimension-2 surface defects in 5d SCFTs engineered by (p, q) 5-brane webs. The three-dimensional defects are realized by D3-branes ending on the brane web. We identify the holographic representation of the defects in Type IIB AdS 6 solutions as probe D3-branes, and study conformal and non-conformal defects which, respectively, preserve one half and one quarter of the supersymmetry. For a sample of 5d SCFTs, including the T N theories, we provide explicit solutions for conformal and non-conformal defects. For the conformal defects we obtain their contribution to the free energy on S 5.
