Maps preserving the sum-to-difference ratio

Sunil Chebolu, Apoorva Khare, Anindya Sen

For a field $F$ , what are all functions $f : F \to F$ that satisfy the functional equation $f \left( (x+y)/(x-y) \right) = (f(x) + f(y))/(f(…

Maps preserving the sum-to-difference ratio in characteristic $p$

Sunil Chebolu, Apoorva Khare, Anindya Sen

Given a field $F$ , we introduce a novel group $S D (F)$ of its self-maps: the solutions $f : F ↠ F$ to the functional equati…

The complexities of falling freely

Anindya Sen, Sunil Chebolu

Suppose you drop a coin from 10 feet above the ground. How long does it take to reach the ground? This routine exercise is well-known to every AP physics and calculus student: the…
