|An integer Pythagorean triple is an integer solution (x, y, z) of the equation
Some of them were known from ancient times. Euclid gave a formula for them. Based on his formula, we have a polynomial Pythagorean triple , with 3 parameters and integer coefficients, which covers all integer Pythagorean triple up to switching x and y. Switching is necessary, but there is a single Pythagorean triple over integer-valued polynomials which covers all integer Pythagorean triples (Frisch-Vaserstein).
Some time ago I reported that the primitive Pythagorean triples, up to switching x and y, can be covered by a polynomial Pythagorean triple (with integer coefficients). My paper in Annals of Mathematics is published in 2010.
In this talk, I consider Pythagorean n-triples. Instead of the sum of 2 squares on the left-hand side, we will have the sum of n-1 squares|
