Ambar Sengupta

Ambar Niel Sengupta is an Indian-American mathematician. He is a professor of mathematics at the University of Connecticut.

Education and career

Ambar Sengupta attended Presidency College, Calcutta and stood first class first in the BSc (Mathematics Honours) examination of the University of Calcutta in 1984. He then joined Cornell University, where he obtained an MS and then a PhD under the supervision of Leonard Gross in 1990.

Professional activities Sengupta's contributions have been in the fields of pure mathematics, mathematical physics, and financial mathematics.

In quantum field theory, Sengupta gave the first rigorous construction of the Yang-Mills measure for compact surfaces, with or without boundary and for bundles of specified topology. He used this to mathematically prove formulas that had been used in the physics literature and discovered new formulas for non-trivial bundles.
