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…

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(…

Rabbit Hunting using Set Theory and Probability

Sunil Chebolu, Deepayan Sarakar

Imagine an invisible rabbit that starts at some unknown integer point $A$ on the number line. At each time step, it hops by a fixed but unknown integer stride $B$ . Both $A$ and $B$ …
