Fortuity and R-charge concentration in the D1-D5 CFT
Chi-Ming Chang, Haoyu Zhang
We investigate finite- BPS cohomology in the D1--D5 CFT, focusing on the sector of fortuitous classes. Analyzing the supercharge cochain complexes in the and theorie…

Fortuity in the D1-D5 system
Chi-Ming Chang, Ying-Hsuan Lin, Haoyu Zhang
We reformulate the lifting problem in the D1-D5 CFT as a supercharge cohomology problem, and enumerate BPS states according to the fortuitous/monotone classification. Working in th…
