etc. Group VI - There are so many old mathematical works which were composed in Sourśeni Prākrta prose and poetry and in Ardhamāgadhi. The quotations of these works found in later works but the original texts are not available. The names of the texts containing such quotations are following - 1. Tatvārthādhigama Sutra Bhāsya of Umāsvati 2. Commentory of Aryabhatiya by Bhaskara - I 3. Dhavata Tikā by Acārya Virasena 4. Commentory of Anuyogadvāra Sūtra by Silanka 5. Litavafi of Bhaskara - II

The well known method of solving quadratic equation given by Sridhara is available in Bhaskara's Lilavati.
चतुराहत वर्गसमै रूपै: पक्षद्वयं गुणयेत्। अव्यक्त वर्गरूपैर्युक्तो पक्षो ततो मूलम्॥ ax2 + bx 4a (ax?) + 4a (bx)
4ac 4a2x2 + 4abx 4a?x? + 4abx + b2
4ac + b2 (2ax + b)2
4ac + b2 2ax + b
# 4ac + b2 -b / 4ac + b2
2a It has been quoted from unavailable work Bijaganita of Sridhara.

Now I am giving the list of the Acāryas/Scholars, who are related with Jaina School and whose works have the material of mathematician's interest. Unless we identify all the available manuscripts and search out the mathematical treatise mentioned by later mathematicians, we cann't claim about the completeness of it. Even then it gives brief idea.
