gadadhar misra -lrb- born 1 march 1956 -rrb- is an indian mathematician who specializes in operator theory .
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 .
misra found counter examples to a conjecture on similarity of operators in the cowen and douglas class .
he gave an explicit description of the class of completely non-unitary contractions whose characteristic function is constant .
he obtained a canonical model as well as complete invariants for a class 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 classification of scalar homogeneous shifts and also calculated the joint taylor spectrum of a class of multiplication operators on the `` twisted '' bergman space .
misra described the holomorphic hermitian vector bundles over the unit disc , which are homogeneous under the action of sl -lrb- 2 , r -rrb- .
he has carried out a complete classification of all irreducible homogeneous operators in the cowen-douglas class .
