Biography
Dr .Tyakal Nanjundiah Venkataramana is an Indian mathematician who specialises in algebraic groups and automorphic forms.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. Venkataramana's first major work was the extension of G A Margulis's work on arithmeticity of higher rank lattices to the case of groups in positive characteristics. He also has contributions to non-vanishing theorems on cohomology of arithmetic groups, on Lefschetz type theorems on restriction of cohomology on locally symmetric spaces and to arithmeticity of monodromy groups .
Research Interest
Liegroups and Arithmetics groups.
