Ruixiang Zhang, Assistant Professor of Mathematics at the University of California (Berkeley, USA) will be awarded the SATRA Ramanujan Award for 2023 for his outstanding contributions to mathematics.Dr. Zhang is a young mathematician whose fundamental work spans analytic number theory, combinatorics, Euclidean harmonic analysis, and geometry. The annual cash prize of US$10,000 will be presented at SASTRA University in Kumbakonam, the hometown of mathematician Srinivasa Ramanujan, during December 20 and 22. To be given at an international conference on the theory.
Sastra Ramanujan Award
- SASTRA Ramanujan Prize is awarded by the Shanmugh Academy of Arts, Science, Technology and Research (SASTRA), Kumbakonam since 2005.
- Inspired by Ramanujan’s achievements in his short life of 32 years, the age limit for the award has been set at 32 years.
Srinivasa Ramanujan
- Ramanujan was born on 22nd December 1887 in the village Erode (400 km from Chennai, then known as Madras).
- The famous British mathematician Godfrey Harold Hardy recognised his talent in 1913. He went to Cambridge, on Godfrey Harold Hardy’s invitation.
- Ramanujam made substantial contributions to the analytical theory of numbers and worked on elliptic functions.
- He also worked on the partition of the whole number, hypergeometric series and Euler’s constant.
- His papers were published in English and European journals, and in 1918 he was elected to the Royal Society of London.
- He died on April 26th, 1920, at the age of 32, just after returning to India after a long illness.
- In India, 22nd December is celebrated as National Mathematics Day in the memory of Srinivasa Ramanujan.
Contributions
Formulas and Equations
- Ramanujan compiled around 3,900 results consisting of equations and identities. One of his most treasured findings was his infinite series for Pi.
- He gave several formulas to calculate the digits of Pi in many unconventional ways.
Game Theory
- He discovered a long list of new ideas to solve many challenging mathematical problems, which gave a significant impetus to the development of game theory.
- His contribution to game theory is purely based on intuition and natural talent and remains unrivalled to this day.
Ramanujan’s Book
- One of Ramanujan’s notebooks was discovered by George Andrews in 1976 in the library at Trinity College. Later the contents of this notebook were published as a book.
Ramanujan number
- 1729 is known as the Ramanujan number.
- It is the smallest number which can be expressed as the sum of two different cubes in two different ways.
- 1729 is the sum of the cubes of 10 and 9 – cube of 10 is 1000 and cube of 9 is 729 adding the two numbers results in 1729.
- 1729 is also the sum of the cubes of 12 and 1, cube of 12 is 1728 and cube of 1 is 1 adding the two results in 1729.
