Leading mathematicians came to Temple Nov. 11-12 for a conference honoring former Temple mathematics professor and researcher Marvin Knopp. A member of Temple’s mathematics faculty since 1976, Knopp was a leading expert in the theory of modular forms and a pioneering figure in the theory of Eichler cohomology, modular integrals, and generalized modular forms. He passed away in December at the age of 78.
