Here are well-known Jaina scholars who made significant mathematical contributions in their era:

• Mahavira (Mahaviračārya) – 9th century. Wrote Ganita-sāra-saṅgraha (Ganita Sara Sangraha), an early comprehensive Indian mathematics text that focuses on algebra and arithmetic. He is regarded as the first Indian mathematician to present mathematics largely independent of astrology.
• Virasena (Veerasena) – late 8th to early 9th century. A renowned Digambara teacher and scholar who, besides his Jain exegetical work, engaged in mathematical ideas. He is credited with developing methods related to the 2-adic valuation and other mathematical notions; he also contributed to the Dhavala commentary on the Shatkhandagama, through which mathematical concepts circulated in Jain scholastic circles.
• Yativṛṣabha (Jadivasaha) – 6th century. A monk and mathematician who authored Tiloyapannatti, a text that includes mathematical and cosmological ideas, including discussions about infinity and related concepts.
• Kumudendu Muni – around 9th–10th century. A Jain monk and polymath traditionally linked with Siribhoovalaya, a remarkable Kannada work that encodes diverse subjects, including mathematical and scientific content, in intricate numerical and cipher schemes.
• Jinasena (and the broader Virasena lineage) – 9th–10th century. While best known for religious literature (e.g., Adi Purana), his close association with Virasena and the Dhavala tradition helped embed mathematical discussions within Jain scholasticism.

Notes:

• These figures are prominent in Jain historical accounts for intertwining mathematics with Jain philosophy, astronomy, and literature. The exact emphasis and details can differ between Digambara and Śvetāmbara traditions, but all are recognized for advancing mathematical thought within the Jain scholarly milieu.
• If you want a short, digestible summary of each figure’s mathematical contributions in Jain contexts, I can tailor it to a specific tradition (Digambara or Śvetāmbara).
