Weierstrass’ Elliptic Function Solutions to the Autonomous Limit of the String Equation

Abstract

In this article, we study the string equation of type (2, 2n + 1), which is derived from 2D gravity theory or the string theory. We consider the equation as a 2n-th order analogue of the first Painlev éequation, take the autonomous limit, and solve it concretely by use of the Weierstrass' elliptic function.
