Parameśvara (1380-1460 CE) [1]was a major Indian mathematician and astronomer of the Kerala school of astronomy and mathematics founded by Mādhava of Saṅgamagrāma. Parameśvara was born into a Namputiri Brahmana family who were astrologers and astronomers. He played an important part in the remarkable developments in Mathematics which took place in Kerala in the late 14th and early part of the 15th century.[2]
Parameśvara proposed several corrections to the astronomical parameters which had been in use since the times of Āryabhaṭa based on his eclipse observations. The computational scheme based on the revised set of parameters is known as Dṛk system. Dṛggaṇita is the text composed based on this system.
His works are mentioned below.
