A Classification of Autoparatopisms of Latin Cubes

Vindula Kumaranayake

A paratopism is an action on a Latin hypercube of dimension d and order n which is an element of the wreath product $S_{n} ≀ S_{d + 1}$ . A paratopism is said to be an autoparatopism…

On Star critical Ramsey numbers related to large cycles versus complete graphs

C. J. Jayawardene, W. C. W. Navaratna

Let $K_{n}$ denote the complete graph on $n$ vertices and $G, H$ be finite graphs. Consider a two-coloring of edges of $K_{n}$ . When a copy of $G$ in the first color, red, or a copy of…

All Ramsey $(C_{n}, K_{6})$ critical graphs for large $n$

Chula J. Jayawardene, W. Chandanie W. Navaratna, J. N. Senadheera

Let $G$ and $H$ be finite graphs. If for any two-coloring of the edges of a complete graph $K_{n}$ , there is a copy of $G$ in the first color, red, or a copy of $H$ in the second col…

A Ramsey problem related to butterfly graph vs. proper connected subgraphs of K4

Chula Jayawardene, Lilanthi Samarasekara

A graph on 5 vertices consisting of 2 copies of the cycle graph C3 sharing a common vertex is called the Butterfly graph (B). The smallest natural number s such that any two-colour…
