*“Mock Modularity of Twisted Index in CHL Models"*
*
*

_Abstract_
We study the twisted partition function of quarter BPS states in CHL 
models and show that for a large class of single-centered black holes, 
the degeneracy of microstates is given by the Fourier coefficients of 
mock Jacobi forms. We identify a class of charges, for which the above 
identification does not hold. We also present the multiplicative lift 
construction of the partition function and comment on the additive lift 
of the same.

*“Matrix Model and Large N Analysis of Knot, Link and LMOV Invariants"*
_
__Abstract_
This talk investigates the reformulation of knot and link invariants as 
correlation functions in unitary matrix models, within the framework of 
Chern-Simons theory. In the double-scaling limit with fixed ’t Hooft 
coupling, Wilson loop operators simplify to trace insertions, enabling a 
systematic large N expansion of correlators. Leading and subleading 
contributions, structured through connected correlators, distinguish 
topological configurations and encode the interaction content of knot 
and link observables. Focusing on the Labastida–Mariño–Ooguri–Vafa 
(LMOV) invariants, we analyze their generating function and compute the 
large N behavior of its coefficients, demonstrating that connected 
correlators contribute to key terms and reveal the asymptotic structure 
of the LMOV invariants.
