This volume contains a collection of 30 of the 51 papers that David Mumford wrote in algebraic geometry. The volume divides Mumford’s papers into three broad areas, each preceded by an easy summarizing the results and outlining their influence on further developments by David Gieseker, George Kempf, Herbert Lange and Eckart Viehweg.Further generations of researchers in this field, graduate students, mathematical physicists, and mathematical historians will profit a great deal from this collection of selected papers.
