Conjeevaram Srirangachari Seshadri (born February 29, 1932 – died July 17, 2020) was a famous Indian mathematician. He was the person who started and led the Chennai Mathematical Institute for many years. He is best known for his important work in a field of math called algebraic geometry.
A special math idea called the Seshadri constant is named after him. He also worked closely with another mathematician, M. S. Narasimhan. Together, they proved the Narasimhan–Seshadri theorem. This theorem helps us understand special math objects called stable vector bundles.
For his amazing contributions, he received the Padma Bhushan award in 2009. This is one of the highest honors a civilian can get in India.

Early Life and Education
Seshadri was born into a Hindu family in Kanchipuram, Tamil Nadu, India. He loved mathematics from a young age. He earned his first degree in math from Madras University in 1953. There, he had great teachers who guided him.
Later, he continued his studies and earned his PhD from Bombay University in 1958. His supervisor, K. S. Chandrasekharan, helped him a lot. In 1971, he was chosen as a Fellow of the Indian Academy of Sciences, which is a big honor.
His Work and Leadership
Seshadri spent many years working at the Tata Institute of Fundamental Research in Bombay. He started there in 1953 and became a senior professor. From 1984 to 1989, he worked at the Institute of Mathematical Sciences, Chennai.
His biggest achievement was starting the Chennai Mathematical Institute (CMI) in 1989. He was the founding director of CMI until 2010. After that, he became the Director-Emeritus, meaning he continued to be an important advisor until he passed away in 2020. He also helped judge the Infosys Prize for mathematics in 2010 and 2011.
Visiting Other Universities
Professor Seshadri was invited to teach and share his knowledge at many famous universities around the world. These visits showed how respected his work was globally.
- University of Paris, France
- Harvard University, USA
- UCLA, USA
- Brandeis University, USA
- University of Bonn, Germany
- Kyoto University, Japan
He also gave talks at the ICM, which is a very important meeting for mathematicians worldwide.
Awards and Honors
Throughout his life, C.S. Seshadri received many awards and honors for his outstanding work in mathematics.
- Honorary degree from Université Pierre et Marie Curie, Paris (2013)
- Honoris Causa from University of Hyderabad, India
- Padma Bhushan (one of India's highest civilian awards)
- Shanti Swarup Bhatnagar Award (a top science award in India)
- Srinivasa Ramanujan Medal from the Indian Academy of Sciences
- Honorary D.Sc. from Banaras Hindu University
- TWAS Science Award
- Fellow of the Indian Academy of Sciences and the Royal Society
- Member of the United States National Academy of Sciences
- Fellow of the American Mathematical Society (2012)
His Mathematical Discoveries
Seshadri's main area of study was algebraic geometry. This field uses algebra to solve problems about shapes and spaces. His work with M. S. Narasimhan on special math objects called unitary vector bundles was very influential. Their Narasimhan–Seshadri theorem changed how mathematicians understood these objects.
He also did important work on Geometric Invariant Theory and Schubert varieties. He introduced something called standard monomial theory. This theory is now widely used and recognized by mathematicians around the world. His discoveries have helped many other mathematicians in their research.
