Kautilya, also known as Chanakya, is considered the father of modern economics due to his contributions to the field of economics and political science. His work, the Arthashastra, is an ancient Indian treatise on statecraft, economic policy, and military strategy.

The Sulba Sutras are a collection of ancient Indian mathematical texts that contain the earliest known formulation of the Pythagorean theorem. These texts were written between 800 and 500 BCE and provide insights into the mathematical knowledge of ancient India.

Brahmagupta, an Indian mathematician and astronomer, introduced the concept of zero as a number in the 7th century CE. He also developed methods for solving quadratic equations and made significant contributions to the field of astronomy.

The Madhava-Gregory Series is an infinite series that is used to calculate the value of pi. It was discovered by the Indian mathematician Madhava of Sangamagrama in the 14th century and later rediscovered by the English mathematician James Gregory in the 17th century.

Bhaskara II, an Indian mathematician and astronomer, developed the concept of the golden ratio in the 12th century CE. He also made significant contributions to the fields of algebra, geometry, and trigonometry.

Indian mathematics influenced the development of economic thought in the West through a combination of factors, including the translation of Indian mathematical texts into Latin, the travels of Indian mathematicians to Europe, and the establishment of trade routes between India and Europe.

The concept of the derivative, which was developed by Indian mathematicians in the 12th century CE, was used by economists to develop the theory of marginal utility. This theory states that the additional satisfaction derived from consuming an additional unit of a good or service decreases as more units are consumed.

Indian mathematics contributed to the development of game theory through the development of the concept of zero-sum games, the concept of Nash equilibrium, and the concept of cooperative games.

Indian mathematics contributed to the development of the theory of risk and uncertainty through the development of the concept of probability, the concept of expected value, and the concept of variance.

Indian mathematics influenced the development of econometrics through the development of statistical methods, mathematical models, and computer algorithms.

Srinivasa Ramanujan, an Indian mathematician, made significant contributions to the field of mathematical economics. He developed new methods for solving problems in number theory and analysis, which have been applied to economic problems.

Indian mathematics contributed to the development of operations research through the development of linear programming, integer programming, and dynamic programming.

Amartya Sen, an Indian economist and philosopher, is known for his work on game theory and social choice theory. He has made significant contributions to the fields of welfare economics, development economics, and political philosophy.

Indian mathematics influenced the development of information economics through the development of information theory, game theory, and auction theory.

Rama Cont, an Indian-French mathematician, is known for his work on mathematical finance. He has made significant contributions to the fields of stochastic analysis, financial mathematics, and econometrics.
