[20 August 2000] This course will be co-taught by Professors Hultquist and Rosenberger. Dr. Hultquist will begin the course, and teach approximately the first half of the course. Since Rosenberger has been on leave at the National Science Foundation with duties through August 2000 and into the Fall, he would be unable to begin the course without disruption, and will teach mostly the last half of the course. We applogize for any inconvenience this may cause. JLR and RAH
