Heron Angles, Heron Triangles, and Heron Parallelograms
Walter Wyss
Heron angle: both its sine and cosine are rational Heron triangle: all its sides and area are rational Heron Parallelogram: all its sides, diagonals and area are rational We give o…
Two Non-Commutative Binomial Theorems
Walter Wyss
We derive two formulae for (A + B)^n, where A and B are elements in a non-commutative, associative algebra with identity.
On Rational Points on the Elliptic Curve E(q) : p2 + q2 = r2(1 + p2q2)
Walter Wyss
We look at the elliptic curve E(q), where q is a fixed rational number. A point (p,r) on E(q) is called a rational point if both p and r are rational numbers. We introduce the conc…
No Perfect Cuboid
Walter Wyss
A rectangular parallelepiped is called a cuboid (standing box). It is called perfect if its edges, face diagonals and body diagonal all have integer length. Euler gave an example w…
Sums of Squares Bijective Parameter Representation
Walter Wyss
We give a bijective parameter representation for a sum of squares of numbers being equal to another sum of squares of numbers.
Evolution, its Fractional Extension and Generalization
Michelle M. Wyss, Walter Wyss
The evolution of a quantity, described by a function of space and time, relates the first derivative in time of this function to a spatial operator applied to the function. The ini…
