CombinaTexas Conferences

CombinaTexas 2020

Due to the coronavirus concerns, CombinaTexas 2020 is cancelled. We will notify the registered participants shortly.

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.

There is also a shuttle service from Bush Intercontinental Airport and Hobby Airport in Houston and a shuttle service from Austin-Bergstrom Airport.


Hotel reservations for registered participants who receive financial support will be arranged and billed through the Mathematics Department. Details of your reservation will be sent to the provided email address at least one weeks prior to the conference. Participants will be housed at the The George at College Station or Cavalry Court College Station . Both are in the new Century Square and within walking distance to Blocker. Graduate students should expect to share a room. If you are not receiving financial support from the conference, you can stay in any hotel in town. Below are some hotels that are within walking distance to the conference site. Please check the rate and availability with the hotels directly.

Warning: Please be aware of a new scam, a "room poacher" email, which pretends to be the housing bureau for CombinaTexas. This is a new scam -- described on P285 of the February Notices. They were from: . Please ignore that email if you receive it.
If you receive financial aid from CombinaTexas 2020, all the hotel reservation will be handled by the Math Dept of TAMU. Please contact the organizers if you have any questions. Otherwise you should make your own reservation. There is no third party that does the housing reservation for CombinaTexas.
