On the BV formalism of open superstring field theory in the large Hilbert space

AbstractWe construct several BV master actions for open superstring field theory in the large Hilbert space.

Hyperunified field theory and gravitational gauge–geometry duality

A hyperunified field theory is built in detail based on the postulates of gauge invariance and coordinate independence along with the conformal scaling symmetry. All elementary particles are merged ... elementary particles are correlated with the geometric properties of hyper-spacetime. To build a reliable unified field theory within the framework of gravitational quantum field theory [68], we shall work

A Cohomological Perspective on Algebraic Quantum Field Theory

Algebraic quantum field theory is considered from the perspective of the Hochschild cohomology bicomplex. This is a framework for studying deformations and symmetries. Deformation is a possible ... constructing interacting QFT models. Symmetry is the primary tool for understanding the structure and properties of a QFT model. This perspective leads to a generalization of the algebraic quantum field theory

The topology of Double Field Theory

North Carolina , USA We describe the doubled space of Double Field Theory as a group manifold G with an arbitrary generalized metric. Local information from the latter is not relevant to our discussion ... and so G only captures the topology of the doubled space. Strong Constraint solutions are maximal isotropic submanifold M in G. We construct them and their Generalized Geometry in Double Field Theory on
