Indian mathematicians have made significant contributions to the field of mathematics, like introducing the concept of zero and place-value arithmetical notation. Indian mathematicians are considered amongst the best in the world who have guided the future generations of mathematicians with their varied works. Indian mathematicians date back to

Indus Valley Civilization and

Vedas. Some of the renowned Indian mathematicians during the early

Vedic Period include names like

Apastamba,

Aryabhata,

Katyayana, Manava,

Yajnavalkya, Baudhayana and

Panini. Renowned mathematician Baudhayana was also a priest and a noted author. Apastamba's Dharmasutra constitutes a part of the superior

Kalpasutra that contains around 30 prasnas, literally means questions. Aryabhata formulated and introduced the concept of Zero. In Dharmasutra, the subjects are well organised and interestingly they are conserved in good condition. In 750 AD, Shridhara composed Patiganita Sara, which is a book on algebra.

**Classical Indian Mathematicians **
From the classical age,

Aryabhata I is one of the most popular and actually the first one in the list of Indian mathematicians-astronomers. He has contributed significantly in the field of mathematics. The most well-known works of Aryabhata include, Aryabhatiya and Arya-Siddhanta.

Bhaskara I was a renowned 7th century Indian mathematician. He is the first one to write numbers in Hindu-Arabic decimal system, and who gave a unique and remarkable rational approximation of the sine function in his interpretation on Aryabhata's work.

Jayadevawas a popular Indian mathematician of 9th century. He mainly worked on Chakravala method or cyclic method. Further, he also made some significant offerings to combinatory.

Brahmagupta was also a popular mathematician of the early age. In Brahmagupta's work, Pell's equation was of prime importance. Bhaskaracharya was also a notable mathematician of the early age and his work had given an algorithmic approach.

Mahavira from south India was a prominent mathematician of the 9th century. His work had given special emphasis on problems related to quadratic and cubic equations. In fact his contribution played a prominent role in the development of mathematics in south India. Madhava was also a prominent mathematician of 14th century and his works included detection of elements that are related to differential calculus. He had also given an approximation of pie. Moreover, Madhava had started a school of mathematics in the state of

Kerala and some notable followers of that school were Nilakantha and Jyesthadeva.

Gopala was also one of the well-known Indian mathematicians.

**Modern Indian Mathematicians **
Manjul Bhargava, another noted mathematician of the modern era is known for composing the law for ternary quadratic forms. The work of Manjul Bhargava bears a deep approach and serves as a mathematical guidance. Harish Chandra on the other hand was not a much famous mathematician but his work had formed the base of Langlands's concept of automorphic forms that are an enormous simplification of the modular forms.

Some of the famous Indian mathematicians of the later age are

S. Ramanujan, A. A. Krishnaswami Ayyangar, P. C Mahalanobis, D. K. Ray-Chaudhuri, Harish-Chandra, Calyampudi Radhakrishna Rao, Shreeram Shankar Abhyankar, Ramdas Lotu Bhirud, Jayant Narlikar and many others. In all probability S.Ramanujam is most famous amongst the modern mathematician of India. He had produced wonderful results in the number theory but his most renowned discovery in the field of mathematics arithmetic theory of modular forms. In a paper, which he had presented in 1916, he had initiated the study of pie function.

Other noted Indian mathematicians from various ages include,

Aryabhata II,

Bhaskara II,

Varahamihira, Nilakantha Somayaji, Jagannatha Samrat, Gadadhara Bhattacharya, Narayana Pandit, Vinod Johri, Biswatosh Sengupta, Narendra Karmarkar, M. S. Raghunathan, Akshay Venkatesh, Sucharit Sarkar, Vijay Kumar Patodi, Navin M. Singhi, Kannan Soundararajan, S. S. Shrikhande, C. S. Seshadri, K. S. S. Nambooripad, L. Mahadevan, Manjul Bhargava, Chandrashekhar Khare and others.
