Kaleidoscopes, Waves and the Prepotential
Rafael Álvarez-García, Fabian Ruehle
Isomorphic flops are topology-changing transitions connecting two diffeomorphic families of Calabi-Yau threefolds. They correspond to the generators of certain Coxeter groups actin…

Harmonic Analysis of the Instanton Prepotential
Rafael Álvarez-García, Fabian Ruehle
Discrete symmetries of Calabi-Yau moduli spaces, generated by isomorphic flops, constrain the instanton expansion of the 4D Type~IIA prepotential. We show that the…
