Combinatorial Diophantine equations
Publicationes Mathematicae Debrecen, 2000For a positive integer \(k\) let \(P_k(x)=x(x+1)\ldots (x+k-1)\) and \(S_k(x)=1^k+2^k+\ldots +x^k\). In the paper the following Diophantine equations are solved (or resolved): \(P_6(x)=P_4(y)\), \(P_6(x)={y\choose 2}\), \(P_6(x)={y\choose 4}\), \({x\choose 3}=P_2(y)\), \({x\choose 3}=P_4(y)\), \({x\choose 6}=P_2(y)\), \({x\choose 6}=P_4(y)\), \({x ...

Quadratic diophantine equations
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1960Tartakowsky (1929) proved that a positive definite quadratic form, with integral coefficients, in 5 or more variables represents all but at most finitely many of the positive integers not excluded by congruence considerations. Tartakowsky’s argument does not lead to any estimate for a positive integer which, though not so excluded, is not represented ...

Abstract As an appetizer, here is a typical problem of the kind Sections 1–5 should equip you to solve. You are invited to try it as soon as you wish. You may find it hard for now, but by the end of Section 5, where its solution is given, it should not look difficult to you.

Abstract Diophantus worked in Alexandria probably in the middle of the third century AD (some authors suggest early in the second century AD). His six or seven surviving books show that he had a highly developed understanding of many number theoretical problems.

Abstract A basic property of integers is that they can be expressed uniquely as a product of prime numbers. In this chapter we investigate other rings having a similar type of unique factorization property. As a means of motivating our investigation, let us begin by considering two number theoretic puzzles involving so-called Diophantine
