Almost Empty Monochromatic Triangles With Many Colors

Bhaswar B. Bhattacharya, Sandip Das, Sk Samim Islam +2

Given integers $c \geq 2$ and $s \geq 0$ , let $M_{3} (c, s)$ denote the least integer such that every set of at least $M_{3} (c, s)$ points in the plane, no three on a line…

An Improved Upper Bound for the Turán Number of the Hexagon

Sandip Das, Sk Samim Islam, Aashirwad Mohapatra +1

For a graph $F$ , the Turán number $ex (n, F)$ is the maximum number of edges in an $n$ -vertex graph containing no copy of $F$ . Determining the Turán numbers of even cy…

On the Number of Almost Empty Monochromatic Triangles

Bhaswar B. Bhattacharya, Sandip Das, Sk Samim Islam +3

In this paper, we consider the problem of counting almost empty monochromatic triangles in colored planar point sets, that is, triangles whose vertices are all assigned the same co…
