On September 20 of 1717, Colin Maclaurin was appointed to the Mathematics Chair at Marischal College, Aberdeen at the age of 19. This is the youngest at which anyone has been appointed a full professor at a university.
On this day of 1793, George Green was born. He was a mathematician best-known for Green's function and Green's theorems in potential theory. Check out the following Communications in Algebra paper related to Green functors! tandfonline.com/doi/full/10.10…

Hochschild Constructions for Green Functors
Let G be a finite group, and R be a commutative ring. If A is a Green functor for G over R, and Γ is a crossed G-monoid, then the Mackey functor AΓ obtained by the Dress construction has a natura...

On this day (but in 1707), Leonhard Euler was born in Basel, Switzerland. Euler is the most prolific mathematician of all time. To honor him, we highlight the following Communication in Algebra paper related to the Euler's local characteristic: tandfonline.com/doi/full/10.10…
On this day of 1642, Isaac Newton was born in Lincolnshire, England (according to the pre-1752 English calendar). Check the following paper about Newton polygons. Merry Christmas and Happy 2024! tandfonline.com/doi/full/10.10…
On this day but in 1640, Fermat announced his "little theorem" in a letter to Bernard Frenicle de Bessey. Check the following Comms. Algebra paper on a generalization of Fermat's little theorem: tandfonline.com/doi/full/10.10…

Fermat’s little theorem and Euler’s theorem in a class of rings
Considering Zn the ring of integers modulo n, the classical Fermat-Euler theorem establishes the existence of a specific natural number φ(n) satisfying the following property: xφ(n)=1 for all x be...
On this day of 1648, Blaise Pascal performed experiments to confirm the theory of atmospheric pressure and the existence of a vacuum. Take a look at the following paper, which introduces a generalization of his famous arithmetical triangle: tandfonline.com/doi/full/10.10…
On this day of 1855, James J. Sylvester began his duties as math professor at the Royal Military Academy, Woolwich, England. His tenure at Woolwich was one of the richest research periods of his life. Check out the following paper honoring his work: tandfonline.com/doi/full/10.10…

Symmetric interpolation, Exchange Lemma and Sylvester sums
The theory of symmetric multivariate Lagrange interpolation is a beautiful but rather unknown tool that has many applications. Here we derive from it an Exchange Lemma that allows to explain in a s...
