In this paper we define a subset of metric preserving functions and give some examples and a characterization ofthis subset.

The p-adic completion ℚ p of the rational numbers induces a different absolute value |⋅| p than the typical | ⋅| we have on the real numbers. In this paper we compare and contrast functions f : ℝ+ → ℝ+, for which the composition with the

It is well-known that despite being a small set in the unit interval, the sum of a Cantor set and itself is the interval [0, 2]. In this paper we look for an analogous result on a different small set, the Golden Ana set.

This chapter takes a classic puzzle about coin-flipping and extends it to a roulette wheel. It examines Penney's Game, a two-player game played via the flipping of a fair coin. Player I picks a sequence of heads (H) or tails (T) of length three (it c

We consider the relationship between separately continuous functions and separately open sets, and we study the properties of the separately open topology on R2 and on Q2. We show that R2 with this topology (denoted R ⊗R) is completely and strongly
