Surindar Kumar Trehan
Surindar Kumar Trehan (S.K. Trehan) was an Indian mathematician who specialised in non-linear stability in magnetohydrodynamics. He was awarded in 1976 the Shanti Swarup Bhatnagar Prize for Science and Technology, the highest science award in India,  in the mathematical sciences category. Prof. Trehan has done significant work on stability of force-free magnetic fields, stability of
jets and cylinders and stability of inhomogeneous plasmas. His work on the mathematical treatment of gaseous polytropes in the presence of a magnetic field is a breakthrough in this  area. He has also done important work on hydromagnetic waves and rotating gaseous
masses. Short Biography
