(Department of Mathematics and Statistics, Amherst College) The original version of a paper, published in 1995. The paper introduced the homogeneous coordinate ring of a toric variety (now called the total coordinate ring or Cox ring) and gave a quotient construction. The paper also studied sheaves on a toric variety, and in Section 4 described its automorphism group. The homogeneous coordinate ring of a toric variety The homogeneous coordinate ring of a toric variety [Erratum] Cox, David A. (Department of Mathematics and Statistics, Amherst College) An erratum that corrects an error in the proof of Proposition 4.3 in the paper "The Homogeneous Coordinate Ring of a Toric Variety." The error in the proof of Proposition 4.3 resulted from the faulty assumption that a certain set of graded endomorphisms forms a ring; rather, it is a monoid under composition. The erratum notes this error and gives a correct proof of the proposition. The homogeneous coordinate ring of a toric variety [Erratum]
