(Non)renormalizability of the D -deformed Wess-Zumino model
We continue the analysis of the D-deformed Wess-Zumino model that we introduced in M. Dmitrijevic and V. Radovanovic, J. High Energy Phys. 04 (2009) 108. The model is defined by a deformation that isExpand

Twisted supersymmetry: Twisted symmetry versus renormalizability
We discuss a deformation of superspace based on a Hermitian twist. The twist implies a *-product that is noncommutative, Hermitian and finite when expanded in a power series of the deformationExpand

Weakly curved background T-duals
We discuss the generalized T-dualization procedure, its connection to the standard procedure, and the results of its application to the arbitrary set of coordinates of the closed string moving in theExpand
Complete T-Dualization of a String in a Weakly Curved Background
We apply the generalized Buscher procedure, to a subset of the initial coordinates of the bosonic string moving in the weakly curved background, composed of a constant metric and a linearlyExpand
Simultaneous T-dualization of type II pure spinor superstring
In this article we consider simultaneous T-dualization of the type II superstring action in a pure spinor formulation. Simultaneous T-dualization means that we make T-dualization at the same timeExpand
Type I background fields in terms of type IIB ones
Abstract We choose such boundary conditions for open IIB superstring theory which preserve N = 1 SUSY. The explicit solution of the boundary conditions yields effective theory which is symmetricExpand

The role of the Seiberg–Witten field redefinition in renormalization of noncommutative chiral electrodynamics
It has been conjectured in the literature that renormalizability of the θ-expanded noncommutative gauge theories improves when one takes into account full nonuniqueness of the Seiberg–WittenExpand

Gauge symmetries decrease the number of Dp-brane dimensions
It is known that the presence of the antisymmetric background field ${B}_{\ensuremath{\mu}\ensuremath{\nu}}$ leads to the noncommutativity of the Dp-brane manifold. The addition of the linear dilatonExpand
