In particular, we establish a recent Cooke's result which asserts that for each positive integer $n$ there are at least $n$ primes between the $(n+1)$th prime and the product of the first $n+1$ primes. Our proof is based on an elementary counting method (enumerative arguments) and ...
Prime number theorem, formula that gives an approximate value for the number of primes less than or equal to any given positive real number x. The usual notation for this number is π(x), so that π(2) = 1, π(3.5) = 2, and π(10) = 4. The prime number t
We analytically obtained the formula for the number of primes in the given range in the concept of two buffer zones. It goes into the empirical formula of Legendre in the limit, i. e., for the first time we gave its rationale. We've done the calculations and comparison with experiment....

The prime number theorem is a statement about the density of primes. Let π(x) denote the number of primes less than or equal to x. Gauss is generally credited with first conjecturing that π(x) is asymptotically li(x) =x 2
The number of primes less thanx.Edmund Landau used π(x) for the number of primes less than or equal toxin 1909 inHandbuch der Lehre von der Verteilung der Primzahlen(Cajori vol. 2, page 36). Letters for the sets of rational and real numbers.The authors of classical textbooks such as ...
On the Representation of a Number as the Sum of Squares and Primes It is clear that the number of distinct representations of a number n as the sum of two primes is at most the number of primes in the interval [n/2, n-2]. We show that 210 is the largest value of n for which ...
He is a high school-esque student who introduces fractions—a numerical quantity that is not a whole number, since he is one third of One Hundred. He also really likes pies as pies are related to fractions, and he's also the humorous announcer for Eleven's (foot)ball matches. ...
A subset \(A\subset \mathcal {P}\) of primes has positive upper density if \(\limsup \limits _{n\to \infty }\frac {|A \cap \mathcal {P}_n|}{|\mathcal {P}_n|} > 0\), where \(\mathcal {P}_n\) is the set of primes less than n. 3. A quadratic form is a polyn...
to many realms in mathematics, including the theory ofDiophantine analysis, divergent series summation (seeinfinite series),Fourier series, theRiemann zeta function, and the distribution of primes. The collaboration between Hardy and Littlewood is one of the most celebrated in 20th-century mathematics....
