Non-Geometric T-Duality as Higher Groupoid Bundles with Connections
Hyungrok Kim, Christian Saemann
We propose a description of T-duality between general geometric and non-geometric backgrounds as higher groupoid bundles with connections. Our description extends the previous obse…
Principal 3-Bundles with Adjusted Connections
Gianni Gagliardo, Christian Saemann, Roberto Tellez-Dominguez
We explore the notion of an adjusted connection for principal 3-bundles. We first derive the explicit form of an adjustment datum for 3-term -algebras, which allows us to…
Topological Classification of Symmetry Breaking and Vacuum Degeneracy
Simon-Raphael Fischer, Mehran Jalali Farahani, Hyungrok Kim +1
We argue that a general system of scalar fields and gauge fields manifesting vacuum degeneracy induces a principal groupoid bundle over spacetime and that the pattern of spontaneou…
Explicit Non-Abelian Gerbes with Connections
Dominik Rist, Christian Saemann, Martin Wolf
We define the notion of adjustment for strict Lie 2-groups and provide the complete cocycle description for non-Abelian gerbes with connections whose structure 2-group is an adjust…
Field Theory Equivalences as Spans of -algebras
Mehran Jalali Farahani, Christian Saemann, Martin Wolf
Semi-classically equivalent field theories are related by a quasi-isomorphism between their underlying -algebras, but such a quasi-isomorphism is not necessarily a homoto…
Adjusting Higher Chern-Simons Theory
Gianni Gagliardo, Dominik Rist, Christian Saemann +1
A fundamental problem in formulating higher Chern-Simons theories is the construction of a consistent higher gauge theory that circumvents the fake-flatness constraint. Here, we pr…
