Normal ordering in string theory and the canonical phase space quantization
Ljubica D. Davidović, Miloš D. Davidović, Milena D. Davidović
We consider quantization techniques with a particular emphasis on the phase space quantization, as encountered in quasi-probabilistic descriptions and in string theory. We investig…
Quantum theory phase space foundations
Miloš D. Davidović, Ljubica D. Davidović, Milena D. Davidović
We give a review of concepts related to connection of classical and quantum theories, from the phase space perspective. Quantum theory is described by non-commutative operators of…
Brackets in bosonic string theory
Ljubica Davidović
We give a review of brackets and interior products in bosonic string theory, in different representations, used in formulation of a theory and derived in a transformation of relate…
Twisted C-brackets
Ljubica Davidović, Ilija Ivanišević, Branislav Sazdović
We consider the double field formulation of the closed bosonic string theory, and calculate the Poisson bracket algebra of the symmetry generators governing both general coordinate…
Courant bracket twisted both by a 2-form and by a bi-vector
Lj. Davidović, I. Ivanišević, B. Sazdović
We obtain the Courant bracket twisted simultaneously by a 2-form and a bi-vector by calculating the Poisson bracket algebra of the symmetry generator in the basis obtained…
Courant bracket as T-dual invariant extension of Lie bracket
Ljubica Davidovic, Ilija Ivanisevic, Branislav Sazdovic
We consider the symmetries of a closed bosonic string, starting with the general coordinate transformations. Their generator takes vector components as its parameter and its…
