   Format: MarkdownItexGlancing through Weigland's [TASI Lectures on F-theory](https://arxiv.org/abs/1806.01854) there's plenty on $(p, q)$ 7-branes. Is there a way to think of why $(p, q)$ is attached to strings, 5-branes and 7-branes?

   Format: MarkdownItexThe D3-brane is thought to be self-dual under S-duality, e.g. [p. 9](https://arxiv.org/pdf/hep-th/9702133.pdf#page=9) in [arXiv:hep-th/9702133](https://arxiv.org/abs/hep-th/9702133). More systematic analysis is in [arXiv:hep-th/9909143](https://arxiv.org/abs/hep-th/9909143), where one needs to compare (2.17)-(2.20) with (2.32)-(2.35). We comment on this in Section 4.3 of the brane bouquet article ([p. 15](https://arxiv.org/pdf/1308.5264.pdf#page=15)).

   Format: MarkdownItexI see, thanks. Another paper on this is [Self-duality in Super D3-brane Action](https://arxiv.org/abs/hep-th/9806161).
