Limits of the inverse scattering problem
Matvei Fedin, Kirill Gubarev, Andrey Morozov
The main goal of tomography is the reconstruction of density function out of its line integrals (integral measurements of this density along x-ray lines). Such construction is poss…
Poly-vector deformations of heterotic supergravity solutions
Kirill Gubarev, Konstantin Sovit
We construct bi- and uni-vector deformations of 10d heterotic supergravity solutions with the gauged double field theory approach. We construct a generalization of the "open/closed…
Brane bound states, deformations and OM
Sergei Barakin, Kirill Gubarev, Edvard T. Musaev
We investigate behavior of brane backgrounds under poly-vector deformations in Type IIB and D=11 supergravities. We find that the standard bi-vector deformations add dissolved F1 s…
Yang-Baxter structure of the extended space
Kirill Gubarev, Edvard Musaev
We construct an analogue of Yang--Baxter deformations defined by a single Killing vector, that is a solution generating transformation in Einstein--Maxwell dilaton theory. We show…
Tri-vector deformations with external fluxes
Sergei Barakin, Kirill Gubarev, Edvard T. Musaev
We extend the formalism of tri-vector deformations to the full SL(5) exceptional field theory with no truncation assumed thus covering 11D backgrounds of any form. We derive explic…
