Rational function semifields of tropical curves are finitely generated over the tropical semifield

JuAe Song

We prove that the rational function semifield of a tropical curve is finitely generated as a semifield over the tropical semifield $\boldsymbol{T} := ( \boldsymbol{R} \cup \{ - \in…

Upper bounds of orders of automorphism groups of leafless metric graphs

Yusuke Nakamura, JuAe Song

We prove a tropical analogue of the theorem of Hurwitz: a leafless metric graph of genus $g \geq 2$ has at most $12$ automorphisms when $g = 2$ ; $2^{g} g!$ automorphisms when $g \ge 3…
