Abstract
Our main question is whether the isomorphism class as a scheme of a curve X over an algebraic closure of a finite field can be reconstructed by the etale fundamental group of X. Tamagawa answered this question affirmatively when the genus of X is 0. In this paper, we will discuss the genus 1 case, and prove a similar result when the genus of X is 1, the cardinality of cusps is 1, and the characteristic of X is not equal to 2.
