About

Enumerative combinatorics is a dynamic subfield of the mathematical sciences with many challenging research problems, ingenious and sophisticated techniques, and important applications in various scientific fields. Questions from a broad range of areas, including algebra, topology, probability, computer science, physical, chemical and biological sciences, have some surprising hidden combinatorial structures that require enumerative methods for their solution. The aims of this conference are:

• Highlight the recent significant theoretical advances in enumerative and analytic combinatorics.
• Showcase the important new applications of enumerative combinatorics to problems arising in other scientific disciplines.
• Discuss new questions, ideas, and methods of an enumerative nature from various scientific fields.
• Bring together researchers of various backgrounds and experience from several fields whose research utilizes or touches upon enumerative techniques.
