Jyotihshastra: Astral and Mathematical Literature c5.s1.38

c5.s1.38

More closely based on the same prototype, though of shorter extent, are the two adhyāyas devoted to mathematics in the SŚŚ composed by Śrīpati in about 1040: adhyāya 13, vyaktagaṇita, on pāṭī in 55 verses, and adhyāya 14, avyaktagaṇita, on algebra in 37 verses. Many of the verses of SŚŚ 13 appear as sūtras in Śrīpati's Gaṇitatilaka³⁰ to which many examples (some taken from Śrīdhara) have been added. Unfortunately, however, the Gaṇitatilaka does not survive in its entirety. After a paribhāṣā modelled on Mahāvīra's, it proceeds in the normal order, though inserting the mathematics of zero in verse 45, in the middle of its treatment of fractions; this mathematics of zero differs from that in SŚŚ 14, 6. The text breaks off in the middle of the miśrakavyavahāra. A commentary on the Gaṇitatilaka was written by Siṃhatilaka Sūri, the pupil of Vibudhacandra; this Siṃhatilaka wrote a vṛtti on the Bhuvanadīpaka of Padmaprabha Sūri at Vijāpura in 1269.
