Group actions on the tropical Hesse pencil

Research output: Contribution to journal › Article › peer-review

Abstract

Addition of points on the tropical Hesse curve is realized via its intersections with two tropical lines. Then the addition formula for the points on the curve is reduced from the one for the level-three theta functions through the ultradiscretization procedure. In addition, a tropical analogue of the Hessian group G₂₁₆, the group of linear automorphisms acting on the Hesse pencil, is investigated; it is shown that the dihedral group D₃ of degree three is the group of linear automorphisms acting on the tropical Hesse pencil.
