Poincaré Series, 3d Gravity and Averages of Rational CFT
Viraj Meruliya, Sunil Mukhi, Palash Singh
We investigate the Poincaré approach to computing 3d gravity partition functions dual to Rational CFT. For a single genus-1 boundary, we show that for certain infinite sets of leve…

Rational CFT With Three Characters: The Quasi-Character Approach
Sunil Mukhi, Rahul Poddar, Palash Singh
Quasi-characters are vector-valued modular functions having an integral, but not necessarily positive, q-expansion. Using modular differential equations, a complete classification…

Contour Integrals and the Modular S-Matrix
Sunil Mukhi, Rahul Poddar, Palash Singh
We investigate a conjecture to describe the characters of large families of RCFT's in terms of contour integrals of Feigin-Fuchs type. We provide a simple algorithm to determine th…
