Abstract :
We show that all algebraic-geometric codes possess a succinct representation that allows for list decoding algorithms to run in polynomial time. We do this by presenting a root-finding algorithm for univariate polynomials over function fields when their coefficients lie in finite-dimensional linear spaces, and proving that there is a polynomial size representation, given which the root-finding algorithm runs in polynomial time
