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 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

Number theory - Prime number theorem: One of the supreme achievements of 19th-century mathematics was the prime number theorem, and it is worth a brief digression. To begin, designate the number of primes less than or equal to n by π(n). Thus π(10) = 4 because 2, 3, 5, and 7 are the four primes not exceeding 10. Similarly π(25) = 9 and π The prime counting function is the number of primes less than or equal to x. The numbers 2, 11, 17, 29, 41 are first few Ramanujan primes. In other words: Ramanujan primes are the integers R n that are the smallest to satisfy the condition − (/) ≥ n, for all x ≥ R n
