Indian mathematicians have made significant contributions to the development of mathematics and  its applications in various fields, ultimately contributing to India's growth and development. Here are  some notable Indian mathematicians and their contributions: 

Ancient Indian Mathematicians 

1. Aryabhata (476 CE):

Proposed the concept of zero, calculated pi (π) accurately, and made  significant contributions to algebra, geometry, and trigonometry. 

2. Brahmagupta (598 CE):

Made significant contributions to number theory, algebra, and geometry.  His book "Brahmasphuta Siddhanta" is considered a masterpiece of ancient Indian mathematics. 

3. Bhaskara (1114 CE):

Made significant contributions to algebra, arithmetic, and geometry. His book  "Bijaganita" is considered a classic of Indian mathematics. 

Modern Indian Mathematicians 

1. Srinivasa Ramanujan (1887-1920):

Made significant contributions to number theory, and his work  on partitions, elliptic curves, and continued fractions is still widely used today. 

2. Prasanta Chandra Mahalanobis (1893-1972):

Made significant contributions to statistics, and his  work on the Mahalanobis distance is still widely used in data analysis. 

3. Harish-Chandra (1923-1983):

Made significant contributions to representation theory, and his  work on the representation theory of semisimple Lie groups is still widely used today. 

Contemporary Indian Mathematicians 

1. Manjul Bhargava (1974-present):

Made significant contributions to number theory, and was  awarded the Fields Medal in 2014 for his work on algebraic geometry. 

2. Sujatha Ramdorai (1962-present):

Made significant contributions to algebraic geometry and  number theory, and was awarded the Shanti Swarup Bhatnagar Prize in 2004. 

3. Raman Parimala (1948-present):

Made significant contributions to algebraic geometry and number  theory, and was awarded the Shanti Swarup Bhatnagar Prize in 1987. 

These individuals have not only advanced mathematical knowledge but have also inspired  generations of mathematicians and scientists in India.
