12th-century Indian mathematicians

Indian mathematician and astronomer (c.1114–1185)

Hemachandra () was a 12th century Śvetāmbara Jaina ācārya, scholar, poet, mathematician, philosopher, yogi, grammarian, law theorist, historian, lexicographer, rhetorician, logician, and prosodist. Noted as a prodigy by his contemporaries, he gained the title kalikālasarvajña, "the knower of all knowledge in his times" and is also regarded as father of the Gujarati language.

Brahmadeva (c. 1060–1130) was an Indian mathematician. He was the author of Karanaprakasa, which is a commentary on Aryabhata's Aryabhatiya. Its contents deal partly with trigonometry and its applications to astronomy.
