제목 : Connected subgraphs in edge-coloured graphs
초록 :
Whenever the edges of a graph G on n vertices are coloured with r colours, on how many vertices can we find a monochromatic, connected subgraph? In this talk, we consider this Ramsey theory type question and its variants, such as replacing "monochromatic" by "s-coloured" (for some s \le r); asking for a specific type of connected subgraph; and putting a condition on the r-colouring of G. Many open questions will be presented.
This talk is based on a joint survey with Shinya Fujita (Yokohama City University, Japan) and Colton Magnant (Georgia Southern University, USA).
