Explore quantum gravity constraints and their relationship to Calabi-Yau manifold degenerations in this 55-minute conference talk by Max Wiesner presented at BIMSA's ICBS2025. Delve into the intricate mathematical structures that emerge when Calabi-Yau spaces undergo degeneration processes and understand how quantum gravity principles impose fundamental constraints on these geometric transformations. Examine the theoretical framework connecting string theory compactifications to the geometric properties of degenerating Calabi-Yau manifolds, and discover how these insights contribute to our understanding of quantum gravity phenomenology and the mathematical foundations of theoretical physics.
