Abstract Two prime numbers{3,5}.{3,5}→{3+3= 6,3+5=8,5+5=10} →{6,8,10}.{{10}→(5+5=10 = 3 + 7) → 7}Increased by 7 →{3, 5, 7}.{3,5,7}→{ 3+3= 6, 3+5=8, 5+5=10, 5+7=12, 7+7=14}→{ 6,8,10,12,14}.{{14}→(7+7=14 = 3 + 11) → 11} Increased by 11 →{3, 5, 7, 11}.Note changes: {3,5,7}→{ 6,8,10,12,14}→ {3, 5, 7,11}.The same logic would be:{3,5,7,11}→{ 6,8,10,12,14,16}→ {3, 5, 7,11,13}.The same logic would be:{3,5,7,11,13}→{ 6,8,10,12,14,16,18,20}→ {3, 5, 7,11,13,17}.If you expand infinitely in the above specified mode: {3, 5, 7, 11, 13, 17 ,...Get: { 6,8,10,12,14,16,18,20,22,...The above is: the continuity of prime numbers can lead to even continuity.Get: Goldbach conjecture holds.If it is mandatory: Authenticity stops at an even number 2n.{{3, 5, 7, 11 ,...,p1}→{ 6,8,10,12,...,2n}.{3, 5, 7, 11, ...,p1} ↛(2n+2).∀p+∀p≠2n+2 } It can be proved that: It violates the "Bertrand Chebyshev" theorem.∴ {3, 5, 7, 11, 13, ...→{ 6,8,10,12,14,...Get: Goldbach conjecture holds.

AbstractLet x = $\begin{array}{} \displaystyle \{x_n\}_{n=1}^{\infty} \end{array}$ be a sequence of positive numbers, and 𝓙x be the collection of all subsets A ⊆ ℕ such that $\begin{array}{} \displaystyle \sum_{k\in A} \end{array}$xk < +∞. The aim of this article is to study how large the summable subsequence could be. We define the upper density of summable subsequences of x as the supremum of the upper asymptotic densities over 𝓙x, SUD in brief, and we denote it by D*(x). Similarly, the lower density of summable subsequences of x is defined as the supremum of the lower asymptotic densities over 𝓙x, SLD in brief, and we denote it by D*(x). We study the properties of SUD and SLD, and also give some examples. One of our main results is that the SUD of a non-increasing sequence of positive numbers tending to zero is either 0 or 1. Furthermore, we obtain that for a non-increasing sequence, D*(x) = 1 if and only if $\begin{array}{} \displaystyle \liminf_{k\to\infty}nx_n=0, \end{array}$ which is an analogue of Cauchy condensation test. In particular, we prove that the SUD of the sequence of the reciprocals of all prime numbers is 1 and its SLD is 0. Moreover, we apply the results in this topic to improve some results for distributionally chaotic linear operators.

In this paper, we prove that the direct product [Formula: see text], where [Formula: see text] are distinct numbers, is uniquely determined by its complex group algebra. Particularly, we show that the direct product [Formula: see text], where [Formula: see text]’s are distinct odd prime numbers, is uniquely determined by its order and three irreducible character degrees.

AbstractWe give a characterization of polynomials with rational coefficients which take integral values on the prime numbers: to test a polynomial of degree n, it is enough to consider its values on the integers from 1 to 2n —1.

Abstract This paper studies the complexity of languages of finite words using automata theory. To go beyond the class of regular languages, we consider infinite automata and the notion of state complexity defined by Karp. Motivated by the seminal paper of Rabin from 1963 introducing probabilistic automata, we study the (deterministic) state complexity of probabilistic languages and prove that probabilistic languages can have arbitrarily high deterministic state complexity. We then look at alternating automata as introduced by Chandra, Kozen and Stockmeyer: such machines run independent computations on the word and gather their answers through boolean combinations. We devise a lower bound technique relying on boundedly generated lattices of languages, and give two applications of this technique. The first is a hierarchy theorem, stating that there are languages of arbitrarily high polynomial alternating state complexity, and the second is a linear lower bound on the alternating state complexity of the prime numbers written in binary. This second result strengthens a result of Hartmanis and Shank from 1968, which implies an exponentially worse lower bound for the same model.
