Title : From Graph Minors to Dimension Theory: Exploring Interconnections
(Click here for the poster)

ABSTRACT
Graph Minor Theory is one of the most important branches of modern graph theory. Hadwiger’s conjecture states that the chromatic number of a graph is at most the number of vertices in the largest clique minor of it. Hadwiger’s conjecture is considered as one of the deepest open problems in graph theory. I will start my talk by briefly explaining our work in graph minors and Hadwiger’s conjecture.

We have extensively studied dimensional parameters of graphs. The reason behind our interest in geometric representations of graphs was our discoveries of results interconnecting some of the geometrically defined dimensional parameters of graphs like boxicity and cubicity to certain well-studied parameters of graph minor theory. Our extensive exploration of dimension theory revealed the inter-relations between geometrically defined parameters such as boxicity and purely combinatorially defined notions such as partial order dimension.

In this talk, I will also briefly mention our work in other streams of graph theory: Our extensive work on the long standing acyclic edge colorig conjecture and the recent but popular conjectures on rainbow coloring, and the interesting questions that we answered even outside our usual comfort zones.
