[hal-00574623, v2] Averaging along Uniform Random Integers

... Abstract. Motivated by giving a meaning to “The probability that a random integer has initial digit d”, we define a URI-set as a random set E of natural integers such that each n ≥ 1 belongs to E with probability 1/n, independently of other integers. This enables us to introduce two notions of densi ...

... A basic extension of the Dirichlet inequality in Theorem 2.2 privided here uses a pair of irrational numbers and the corresponding parameters. Lemma 8.1. Let α = [a0 , a1 , a2 , . . .] and β = [b0 , b1 , b2 , . . .] be the continued fractions of two distinct irrational numbers α and β ∈ R such that ...

Luckily, nothing changes from when a and b are just real numbers. We will particularly be interested in writing a closed form expression for the sum of c ...

... a certain conjecture of Lang [1] is true, then there exists an upper bound on k for the existence of a rational Diophantine k-tuple. Along these lines, Dujella [3] has shown unconditionally that no Diophantine sextuple exists, and that there are at most finitely many Diophantine quintuples. Although ...

Non-standard calculus

In mathematics, non-standard calculus is the modern application of infinitesimals, in the sense of non-standard analysis, to differential and integral calculus. It provides a rigorous justification for some arguments in calculus that were previously considered merely heuristic.Calculations with infinitesimals were widely used before Karl Weierstrass sought to replace them with the (ε, δ)-definition of limit starting in the 1870s. (See history of calculus.) For almost one hundred years thereafter, mathematicians like Richard Courant viewed infinitesimals as being naive and vague or meaningless.Contrary to such views, Abraham Robinson showed in 1960 that infinitesimals are precise, clear, and meaningful, building upon work by Edwin Hewitt and Jerzy Łoś. According to Jerome Keisler, ""Robinson solved a three hundred year old problem by giving a precise treatment of infinitesimals. Robinson's achievement will probably rank as one of the major mathematical advances of the twentieth century.""
