Modularity, Calabi-Yau geometry and 2d CFTs
Christoph A. Keller
We give a short overview over recent work on finding constraints on partition functions of 2d CFTs from modular invariance. We summarize the constraints on the spectrum and their c…

Constraints on 2d CFT partition functions
Daniel Friedan, Christoph A. Keller
Modular invariance is known to constrain the spectrum of 2d conformal field theories. We investigate this constraint systematically, using the linear functional method to put new i…
