decomposition of denominator formulae of some BKM Lie superalgebras -- II
Suresh Govindarajan, Mohammad Shabbir
The square-root of Siegel modular forms of CHL Z_N orbifolds of type II compactifications are denominator formulae for some Borcherds-Kac-Moody Lie superalgebras for N=1,2,3,4. We…
Positivity of discrete information for CHL black holes
Suresh Govindarajan, Sutapa Samanta, P Shanmugapriya +1
Black holes carry more information about the microstates than just the total degeneracy. As a concrete example, the Z(N)-twined helicity trace indices for 1/4-BPS black holes of th…
decomposition of denominator formulae of some BKM Lie superalgebras
Suresh Govindarajan, Mohammad Shabbir, Sankaran Viswanath
We study a family of Siegel modular forms that are constructed using Jacobi forms that arise in Umbral moonshine. All but one of them arise as the Weyl-Kac-Borcherds denominator fo…
Mathieu Moonshine and Siegel Modular Forms
Suresh Govindarajan, Sutapa Samanta
A second-quantized version of Mathieu moonshine leads to product formulae for functions that are potentially genus-two Siegel Modular Forms analogous to the Igusa Cusp Form. The mo…
Black Hole Hair Removal For N=4 CHL Models
Subhroneel Chakrabarti, Suresh Govindarajan, P Shanmugapriya +2
Although BMPV black holes in flat space and in Taub-NUT space have identical near-horizon geometries, they have different indices from the microscopic analysis. For K3 compactifica…
The Brylinski filtration for affine Kac-Moody algebras and representations of -algebras
Suresh Govindarajan, Sachin S. Sharma, Sankaran Viswanath
We study the Brylinski filtration induced by a principal Heisenberg subalgebra of an affine Kac-Moody algebra , a notion first introduced by Slofstra. The associated…
