タイトル	TROPICALIZATION OF 1-TACNODAL CURVES ON TORIC SURFACES
著者	Takahashi, Takuhiro Takahashi, Takuhiro
抄録	A degeneration of a singular curve on a toric surface, called a tropicalization, was constructed by E. Shustin. He classified the degeneration of 1-cuspidal curves using polyhedral complexes called tropical curves. In this paper, we define a tropical version of a 1-tacnodal curve, that is, a curve having exactly one singular point whose topological type is A_3, and by applying the tropicalization method, we classify tropical curves which correspond to 1-tacnodal curves.
