Project Title

 

Combinatorics and Representation Theory in CFT, ADS/CFT, matrix/tensor models. 

Symmetric groups and their group algebras, along with concepts in representation theory including Schur-Weyl duality, have been applied to the study of half-BPS states in N=4 SYM theory, in particular to clarify the holographic map of the AdS/CFT correspondence. For full details click here
