2012 Conference

General Information

During the Spring of 2012, Fourth Discrete Geometry and Algebraic Combinatorics Conference is organized by the Department of Mathematics of The University of Texas at Brownsville/Texas Southmost College (UTB/TSC). This event is being held from April 18 to April 21, 2012 on South Padre Island. The event is partially supported by the National Security Agency. This conference is a unique opportunity for Geometry and Combinatorics researchers to meet, share their specialized knowledge and learn from others.
