Courant algebroid without constraints on fluxes on its Dirac structures
Ilija Ivanišević, Branislav Sazdović
We examine the standard Courant bracket and its extensions, defined by twists with different transformations relevant to string theory. We analyze Dirac structures on thes…

Fluxes of Courant bracket twisted at the same time by and
Ljubica Davidović, Ilija Ivanišević, Branislav Sazdović
This paper investigates the simultaneous twisting of the Courant bracket by a 2-form and a bi-vector , exploring the generalized fluxes obtained in Courant algebroid relatio…

Courant bracket found out to be T-dual to Roytenberg bracket
Ilija Ivanišević, Ljubica Davidović, Branislav Sazdović
Bosonic string moving in coordinate dependent background fields is considered. We calculate the generalized currents Poisson bracket algebra and find that it gives rise to the Cour…
