2 SHANTA LAISHRAM 2. Lemmas We begin with the following estimates from prime number theory. Recall that p i is the ith prime prime and ˇ( ) is the number of primes . In mathematics, a Ramanujan prime is a prime number that satisfies a result proven by Srinivasa Ramanujan relating to the prime-counting function. Origins and definition. In 1919, Ramanujan published a new proof of Bertrand's postulate which, as he notes, was first proved by

In Section 5, we associate runs of odd Ramanujan primes to certain prime gaps. An appendix explains the algorithm for computing Ramanujan primes and includes a Mathematica program. In 1918, Ramanujan  published a seminal paper entitled \On certain trigono- metric sums and their applications in the theory of numbers" in which he introduced sums (now called Ramanujan …

Most of the entries in number theory fall under the umbrella of classical analytic number theory. Perhaps the most intriguing entries are connected with the classical, unsolved circle and divisor problems. Review from the second volume: "Fans of Ramanujan's

Introduction Results Distribution Conclusion Prime Numbers Any integer can be written as a unique product of prime numbers (Fundamental Theorem of Arithmetic). Ramanujan sums are finite if or is finite. In particular, . Many multiplicative functions on the natural numbers (cf.

In number theory, a branch of mathematics, Ramanujan's sum, usually denoted c q (n), is a function of two positive integer variables q and n defined by the formula: The actual probability of a prime being a c-Ramanujan prime is just the ratio of the number of c-Ramanujan primes in the interval (105 , 106 ] to the total number of primes in that interval. We notice that for c near 1/2, runs of non-c-Ramanujan primes are longer than predicted. Also striking is the large discrepancy in the length of the largest run for expected versus actual c-Ramanujan
