Balanced Metrics Know About SYZ
Per Berglund, Tristan Hübsch, Vishnu Jejjala +2
Numerical Ricci-flat metrics on Calabi-Yau manifolds are becoming increasingly accurate. However, they often lack the interpretability required to extract theoretical insights. In…
What to do with a Ricci-flat Calabi--Yau metric?
Per Berglund, Tristan Hübsch, Vishnu Jejjala
Numerical approximations to Ricci-flat Calabi--Yau metrics make it possible to move beyond the topological and holomorphic data that have traditionally dominated explicit string co…
Chern Characteristics and Todd-Hirzebruch Identities for Transpolar Pairs of Toric Spaces
Per Berglund, Tristan Hübsch
Standard toric geometry methods used to construct Calabi-Yau varieties may be extended to complete intersections in non-Fano varieties encoded by star triangulating non-convex poly…
Information Metrics and Possible Limitations of Local Information Objectivity in Quantum Gravity
Per Berglund, Andrew Geraci, Tristan Hubsch +2
Local information objectivity, that local, independent observers can infer the same information about a model upon exchange of independently acquired experimental data, is fundamen…
Physical limits on information metrics and quantum gravity as gravitized quantum theory
Per Berglund, Andrew Geraci, Tristan Hubsch +2
There is a long history in both general relativity and quantum mechanics of removing fixed background structures, thereby making observed objects and measurement processes dynamica…
Gromov-Witten Invariants and Mirror Symmetry For Non-Fano Varieties Via Tropical Disks
Per Berglund, Tim Gräfnitz, Michael Lathwood
Under mirror symmetry a non-Fano variety corresponds to an instanton corrected Hori-Vafa potential . The classical period of equals the regularized quantum period of …
