摘要翻译:
本文给出了带n个标记点的有理热带曲线模空间的定义。我们证明了该空间具有维数为n-3的光滑热带变体的结构。我们定义了这个空间的Deligne-Mumford紧化和热带$\psi$-类因子。

英文摘要:
This note is devoted to the definition of moduli spaces of rational tropical curves with n marked points. We show that this space has a structure of a smooth tropical variety of dimension n-3. We define the Deligne-Mumford compactification of this space and tropical $\psi$-class divisors.
