Ancient Indian mathematical treatises contain ingenious methods for finding integer solutions of indeterminate (or Diophantine) equations. The three greatest landmarks in this area are the kuṭṭaka method of Āryabhaṭa for solving the linear indeterminate equation ay − bx c c, the bhāvanā law of Brahmagupta, and the cakravāla algorithm described by Jayadeva and Bhāskara II for solving the quadratic indeterminate equation Dx2 + 1 = y2. We shall briefly recall the history of the above equations in… 

Mathematics and Astronomy in India before 300 BCE

Our knowledge about the mathematical accomplishments in India prior to 300 BCE is derived primarily from ancient Sanskrit texts, especially the Vedic and the Vedāṅga treatises. The Vedic literature

Decimal System in India

It is India that gave us the ingenious method of expressing all numbers by means of ten symbols, each symbol receiving a value of position as well as an absolute value; a profound and important idea

Algorithms in Indian Mathematics

A few selected algorithms that are representative of the Indian mathematical tradition from the ancient Śulbasūtrās to the medieval texts of the Kerala School of Mathematics and Astronomy are discussed.

Proofs in Indian Mathematics

Contrary to the widespread belief that Indian mathematicians did not present any proofs for their results, it is indeed the case that there is a large body of source-works in the form of commentaries

History of Mathematics: Why and How

My first point will be an obvious one. In contrast with some sciences whose whole history consists of the personal recollections of a few of our contemporaries, mathematics not only has a history,

Solving the Pell equation

We illustrate recent developments in computational number theory by studying their implications for solving the Pell equation. We shall see that, if the solutions to the Pell equation are properly

Brahmagupta’s Bhāvanā: Some Reflections

We shall present Brahmagupta’s treatment of the indeterminate equation Dx2 + 1 = y2 highlighting some ideas of modern algebra that are implicit in this ancient work of 628 CE and discuss the
