Govindasvāmi
Govindasvāmi was an Indian mathematical astronomer most famous for his Bhasya, a commentary on the Mahābhāskarīya of Bhāskara I, written around 830. The commentary contains many examples illustrating the use of a Sanskrit place-value system and the construction of a sine table.
His work "Govindakriti" was a sequel to Āryabhaṭīya and is lost. His works have been quoted extensively by Sankaranarayana and Udayadivakara and by Nilakantha Somayaji. Sankaranarayana was the director of the observatory founded in mahodayapuram, the capital of the Chera kingdom and is believed to be the student of Govinda Swami. In his book, Sankaranarayana gives explanations to the insightful questions of the king Revivarma, then ruler of Mahodayapuram and from these references the period of Sankaranarayana is known.
It is also believed that the nauka, a bhashya of brihat jathaka of Varahamihira is written by Govinda swami. Some scholars have suggested that the famous Dasadhayi is the abbreviated form of Nauka.
