Ravindra Shripad Kulkarni (born 1942) is an Indian mathematician, specializing in differential geometry. He is known for the Kulkarni–Nomizu product.
Education and career
Ravi S. Kulkarni received in 1968 his Ph.D. from Harvard University under Shlomo Sternberg with thesis Curvature and Metric. For the academic year 1980–1981 he was a Guggenheim Fellow.
After a research and teaching career spanning over 40 years in the US at Johns Hopkins University, Columbia University, Indiana University, and City University of New York, he returned to India as Distinguished Professor and Director of Harish-Chandra Research Institute, one of three research institutes for Mathematics and Theoretical Physics in India, followed by a 7-year stint at the Indian Institute of Technology (Bombay) as Mathematics Chair. He is interested in the philosophy of Mathematics and Science, and notes he has “…not yet figured out the enigma of how Ramanujan’s mind worked”.
He had been the president of the Ramanujan Mathematical Society.
