Kumar Eswaran HYDERABAD: City-based mathematical physicist, Kumar Eswaran, has claimed to have found proof for Riemann Hypothesis (RH), a mathematical problem unsolved for the past 161 years. Considered the top-most mathematical problem of the top 10 unsolved mathematical problems by American mathematician Stephen Smale, the RH fundamentally helps in counting the prime numbers and also gives a method of generating large random numbers. In 2000, it was designated as a millennium problem, one of the seven mathematical problems selected by the Clay Mathematics Institute of Cambridge, Mass, USA. It announced a reward of $1 million dollars for its solution. Kumar Eswaran, a mathematical physicist at Sreenidhi Institute of Science and Technology, Hyderabad placed his research titled ‘the final and exhaustive proof of the Riemann Hypothesis from first principles’ on the internet almost five years ago. In spite of all this, there was a reluctance on the part of the editors of international journals to put the paper through a detailed peer review.
