Abstract
We propose a closed string tachyon action including kinetic and potential terms for non-supersymmetric orbifolds. The action is given in terms of solutions to tt∗ equations which captures the geometry of vacua of the corresponding N = 2 worldsheet theory. In certain cases the solutions are well studied. In case of tachyons of C/Zn, solutions to affine toda equations determine the action. We study the particular case of C/Z3→C in detail and find that the Tachyon action is determined in terms of a solution to Painleve III equation.
