Discussed with Xiaohan about how to glue and smooth a nodal curve (possibly open).

• The story of Kaehler differential. MO
• Rachel Webb's intro to quasi-maps. https://arxiv.org/pdf/1910.07262.pdf
• Okounkov-Pandharipanda, https://arxiv.org/abs/math/0101147 (I don't know what is this about)
• Melissa Liu also talked about how to deal with moduli space of curves with boundary and internal marked points.
