Informal research statement

Abstract

AbstractThe editors are reproducing here an informal research statement that Dan wrote in one of his last years at the University of Maryland. It provides a rare insight into how he viewed his own work and as usual he did an excellent job in setting forth the main points in a clear way. The summary was retyped, lightly edited to correct typos, and provided with references by Ayşe Şahin. One of the editors (B.W.) added a brief appendix to cover some of the highlights of Dan’s work during the last years of his life. Following the research summary is a complete list of Dan’s publications as well as a second list for the other references cited.
