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
