Bridging W-algebras and affine Yangians- from new perspectives

Project description

Bridging the divide: Yangians and W-algebras

Modern physics has revealed mysterious links between four-dimensional gauge theories and two-dimensional conformal field theories, yet the relationship between specific mathematical structures such as cohomological Hall algebras and vertex algebras remains deeply enigmatic. Supported by the Marie Skłodowska-Curie Actions programme, the WAYREP project aims to build a bridge between these algebraic worlds. It is expected to achieve this by establishing a long-sought correspondence between affine Yangians and W-algebras, leveraging recent breakthroughs in the classification of these complex structures. Beyond this, the project will also focus on deepening the understanding of moduli spaces and quantum symmetries. Ultimately, WAYREP’s goal is to foster interdisciplinary dialogue across geometry, algebra, and physics, providing transformative insights into fundamental mathematical laws.

Objective

Recent advances in theoretical physics have significantly deepened our understanding of quantum field theories and uncovered surprising connections between seemingly unrelated areas of mathematics. A key development is the Alday–Gaiotto–Tachikawa correspondence, which links four-dimensional supersymmetric gauge theories with two-dimensional conformal field theories, revealing profound ties between enumerative geometry and the representation theory of vertex algebras. This framework has since expanded into the broader BPS/CFT correspondence, predicting a deep yet still mysterious relationship between cohomological Hall algebras and vertex algebras, incarnating rich combinatorics, tensor categories, and representation theory from different perspectives. Supported by the Marie Skłodowska-Curie Actions programme, the WAYREP project aims to construct a rigorous bridge between these algebraic worlds. It focuses on establishing a long-sought correspondence between affine Yangians and W-algebras, leveraging recent advances in the structure and classification of the latter. Through this approach, WAYREP will contribute to a deeper understanding of moduli spaces, vertex algebras, and quantum symmetries, fostering interdisciplinary dialogue across geometry, algebra, and physics.
