Gadadhar Misra
Gadadhar Misra (born 1 March 1956) is an Indian mathematician who specializes in operator theory. He was born at Bhubaneswar in the state of Odisha to Prof Chakrapani Mishra and Smt Arunabala Mishra. He studied at DM School, BJB College, Sambalpur University (Masters, 1979) and State University of New York in USA (PhD, 1982). He taught at Indian Statistical Ins*ute (ISI), Kolkata and Bengaluru before joining the Indian Ins*ute of Science (IISc), Bengaluru where he is currently engaged in teaching and research.
He was awarded the Shanti Swarup Bhatnagar Prize for Science and Technology in 2001, the highest science award in India, in the mathematical sciences category. He was awarded the Biju Patnaik Award for Scientific Excellence by Odisha Bigyan Academy in 2013. Gadadhar found counter examples to a conjecture on similarity of operators in the Cowen and Douglas cl*. He gave an explicit description of the cl* of completely non-unitary contractions whose characteristic function is constant. He obtained a canonical model as well as complete invariants for a cl* of quotient Hilbert modules, and introduced the notion of quasi-free Hilbert modules to generalize parts of the Sz-Nagy-Foias model theory in the context of multi-variate operator theory. He obtained a cl*ification of scalar *geneous shifts and also calculated the joint Taylor spectrum of a cl* of multiplication operators on the "twisted" Bergman space. Misra described the holomorphic Hermitian vector bundles over the unit disc, which are *geneous under the action of SL (2,R). He has carried out a complete cl*ification of all irreducible *geneous operators in the Cowen-Douglas cl*.
Gadadhar Misra is married to Tanuja Misra and their daughter Neeldhara Mishra is an *istant Professor of Mathematics and Computer Science at IIT, Gandhi Nagar.
