Hide tip ] The module builds on mathematical ideas introduced in MST Essential mathematics 1covering a wide range of topics from different areas of mathematics. The practical application to problems provides a firm foundation for further studies in mathematics and other mathematically rich subjects such as physics and engineering. Topics covered include mathematical typesetting, number theory, conics, statics, geometric transformations, calculus, differential equations, mathematical language and proof, dynamics, eigenvalues and eigenvectors and combinatorics. It also helps develop the abilities to study mathematics independently, to solve mathematical problems and to communicate mathematics.
The basic version of the arithmetic derivative takes positive integers as inputs. The only requirements are the two shown in the picture: It can be proved fairly easily that there is only one function satisfying these requirements. This function is known as the arithmetic derivative, and a formula for it is given at the bottom of the picture in terms of the factorization of n into prime powers.
The table shows the values of the derivatives of the first few positive integers; these values will always be other nonnegative integers. The first person to investigate the arithmetic derivative systematically seems to have been E. Barbeau inalthough the function had previously appeared in as a question on a Putnam Prize competition.
The arithmetic derivative has a number of interesting properties, as well as close connections to some famous problems in number theory. It also allows for the study of differential equations involving natural numbers, using the arithmetic derivative in place of the usual derivative. Both of these results are easy exercises.
The paper contains the above two results but proves many others and offers several conjectures. Some of these conjectures relate to famous open problems in number theory, such as the Goldbach conjecture and the twin prime conjecture.
The Goldbach conjecture is the hypothesis that every even integer greater than 2 can be expressed as the sum of two primes.
Note that this is a one-way implication, and it does not mean that a proof of this differential equation identity would prove the Goldbach conjecture. This is still an open problem, although there have been breakthroughs towards proving this in the last year or so, thanks to work of Yitang Zhang, Terence Tao and others.
As in the case of the other conjecture, this is a one-way implication. There are many generalizations of the arithmetic derivative, some of which are discussed in the paper.
For example, the derivative can be extended to negative numbers by changing the sign, and to rational numbers by requiring the derivative to satisfy the quotient rule.
It can also be extended to unique factorization domains UFDswhich are algebraic systems in which elements can be factorized into primes in an essentially unique way.

This is a vert good question, The Goldbach conjecture is a hard conjecture of additive number theory. Obviously, it stands since almost years, and even the recent breakthrough of Helfgott who made Vinogradow's result effective, completint the proof of the fact that all.

One of the most studied problems in additive number theory, Goldbach’s conjecture, states that every even integer greater than or equal to 4 can be expressed as a sum of two primes.
Additive number theory is concerned with the additive structure of the integers, such as Goldbach's conjecture that every even number greater than 2 is the sum of two primes. One of the main results in additive number theory is the solution to Waring's problem.
Introduction An improved real number system, devoid of the paradoxes of the present system, that was effective in resolving certain fundamental problems in Physics, leading to a grand unified theory, was discussed by Escultura in a number of papers -.
The most fascinating show about design in London this year (and we've had a lot of design shows) is not a design show. Michael Rakowitz's 'The Worst Condition Is To Pass Under A Sword Which Is Not One's Own' at the Tate (on till 3 May) is the most revealing study of how design, fiction, and horrifying reality combine in the strangest of ways.
