What is "yativrsabha"

Yativṛṣabha, also known as Jadivasaha, was a mathematician and Jain monk. He is believed to have lived during the 6th century, probably during 500-570. He lived and worked between the periods of two great Indian mathematicians, Aryabhata (476 – 550) and Brahmagupta (598-668). He wrote the book named Tiloyapannatti which describes cosmology from the point of view of Jain religion and philosophy. "The work also gives various units for measuring distances and time." Tiloya Panatti postulated different concepts about infinity.
