Point sets that minimize $(\leq k)$ -edges, 3-decomposable drawings, and the rectilinear crossing number of $K_{30}$

M. Cetina, C. Hernández-Vélez, J. Leaños +1

There are two properties shared by all known crossing-minimizing geometric drawings of $K_{n}$ , for $n$ a multiple of 3. First, the underlying $n$ -point set of these drawings has exa…

On the number of mth roots of permutations

Jesús Leaños, Rutilo Moreno, Luis Manuel Rivera-Martínez

Let m be a fixed positive integer. It is well-known that a permutation $σ$ may have one, many, or no mth roots. In this note we provide an explicit expression and a generating func…
