Sridhara

Śrīdhara or Śrīdharācārya (8th–9th century) was an Indian mathematician believed to come either from the Bengal region or from South India. Very little is known about his life beyond a few mentions by later mathematicians and the content of his two extant treatises about arithmetic, ''Pāṭī-gaṇita'' and ''Tri-śatikā'', which do not contain biographical details such as his parents, teachers, or birthplace. Based on example problems in his works mentioning Shiva, scholars believe he was probably a Shaivite Hindu. He was mentioned by Bhāskara II (12th century), and made apparent reference to Brahmagupta (7th century). Govindasvāmin (9th century) quoted a passage also found in ''Tri-śatikā'', and overlapping material is found in the work of Mahāvīra (9th century), from which historians estimate Śrīdhara to have lived in the 8th or 9th century.
