CombinaTexas Conferences

CombinaTexas 2023

Welcome to CombinaTexas 2023!

CombinaTexas, a combinatorics conference in the South-Central United States, is an annual regional conference on Combinatorics, Graph Theory, and Computing. It is dedicated to the enhancement of both the educational and research atmospheres of the community of combinatorialists and graph theorists in Texas and the surrounding states. The aim of the CombinaTexas series is to increase communication between mathematicians in the region, promote the research of the regional combinatorics community, and provide a forum for presentation and discussion of developments in the field of combinatorics.
