French mathematician Yves Meyer wins 2017 Abel Prize

French mathematician Yves Meyer has won the prestigious 2017 Abel Prize for his pivotal role in the development of the mathematical theory of wavelets (small waves or ripples).

His theory is used for applications ranging from image compression to the detection of gravitational waves from the merging of black holes. It also allowed scientists to create unique wavelet transforms suited to specific signals.

About Abel Prize

  • It is awarded annually by the Norwegian Academy of Science and Letters to one or more outstanding mathematicians. It is named after Norwegian mathematician Niels Henrik Abel.
  • The award was established by the Government of Norway in 2001. It is described as the mathematician’s Nobel Prize and is one of the world’s top prizes in mathematics
  • It carries monetary award of 6 million Norwegian kroner (NOK) (around 600,000 Euros).
  • Indian American mathematician R. Srinivasa Varadhan was bestowed with this award in 2007 for his fundamental contributions to probability theory and for creating a unified theory of large deviation.

About Wavelets

Wavelets are widely used in signal processing, including in compressing certain formats of JPEG images. They are like their more famous cousins Fourier transforms. They are particularly useful when the goal is to discard some extraneous information (such as low-frequency noise from the universe) while keeping the important signal.

December 22: National Mathematics Day

The National Mathematics Day is observed every year on 22nd December to celebrate birth anniversary of great Indian autodidact Mathematician Srinivasa Ramanujan. This year, it is 129th birth anniversary of Srinivasa Ramanujan.

About Srinivasa Ramanujan

  • Srinivasa Ramanujan was born on 22nd December, 1887 in Erode district of Tamil Nadu. He died at young age of 32 on 26 April 1920.
  • He was considered as doyen of number theory, infinite series, mathematical analysis, and making formulas and equations without any formal training in pure mathematics.He in the same league as great mathematicians such as Euler and Gauss.
  • He was deeply religious person and had credited his mathematical capacities to divinity. He had once said ‘”An equation for me has no meaning, unless it expresses a thought of God.”
  • Key contributions: As a mathematical genius, he had compiled more than 3900 mathematical results and equations.
  • His Ramanujan Prime and Ramanujan theta discoveries have inspired further research on this mathematical subject.
  • Along with British Mathematician Godfrey Harold Hardy, Ramanujan had discovered the smallest number represented as sum of two cubes 1729 which is known as Hardy-Ramanujan number.
  • Autobiography and Movie: The feature film “The Man Who Knew Infinity” was based on his life. It was based on his biography “The Man Who Knew Infinity: A Life of the Genius Ramanujan” written in 1991 by Robert Kanigel.
Background

The National Mathematics Day was instituted in 2011 by the Union Government to celebrate Ramanujan’s 125th birth anniversary. Besides, the year 2012 was also declared National Mathematics Year.
