Surindar Kumar Trehan (S.K. Trehan) was an Indian
mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems.
Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change.

He was awarded in 1976 the
Shanti Swarup Bhatnagar Prize for Science and Technology
The Shanti Swarup Bhatnagar Prize for Science and Technology (SSB) is a science award in India given annually by the Council of Scientific and Industrial Research (CSIR) for notable and outstanding research, applied or fundamental, in biology, ...
, 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.
