Pseudo-Riemannian and Hessian Geometry Related to Monge-Ampère Structures
Radek Suchánek, Stanislav Hronek
We study properties of pseudo-Riemannian metrics corresponding to Monge-Ampère structures on four-dimensional . We describe a family of Ricci flat solutions, which are parame…
The correction from double field theory
Stanislav Hronek, Linus Wulff, Salomon Zacarias
It is known that the order correction to the tree-level effective action for the bosonic and heterotic string can be described in the framework of Double Field Theory (DFT). H…
String theory at order and the generalized Bergshoeff-de Roo identification
Stanislav Hronek, Linus Wulff
It has been shown by Marques and Nunez that the first -correction to the bosonic and heterotic string can be captured in the covariant formalism of Double Field Theory…
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,…
