O(D,D) and the string expansion: An obstruction
Stanislav Hronek, Linus Wulff
Double Field Theory (DFT) is an attempt to make the O(d,d) T-duality symmetry of string theory manifest, already before reducing on a d-torus. It is known that supergravity can be…

Relaxing unimodularity for Yang-Baxter deformed strings
Stanislav Hronek, Linus Wulff
We consider so-called Yang-Baxter deformations of bosonic string sigma-models, based on an -matrix solving the (modified) classical Yang-Baxter equation. It is known that a unim…

Weak inverse problem of calculus of variations for geodesic mappings and relation to harmonic maps
Stanislav Hronek
In this paper, we study the relation between geodesic and harmonic mappings. Harmonic mappings are defined between Riemannian manifolds as critical points of the energy functional,…
