Dynamical noncommutativity and Noether theorem in twisted phi^*4 theory
Paolo Aschieri, Leonardo Castellani, Marija Dimitrijevic
A \star-product is defined via a set of commuting vector fields X_a = e_a^μ(x) \partial_μ, and used in a phi^*4 theory coupled to the e_a^μ(x) fields. The \star-product is dynamica…
Lie derivatives along antisymmetric tensors, and the M-theory superalgebra
Leonardo Castellani
Free differential algebras (FDA's) provide an algebraic setting for field theories with antisymmetric tensors. The "presentation" of FDA's generalizes the Cartan-Maurer equations o…
Supersymmetric domain wall x G/H solutions of IIB supergravity
L. Castellani, L. Sommovigo
1-brane nonmaximally supersymmetric solutions of D=10 chiral supergravity are discussed. In the dual frame, their near brane geometry is the product of a 3-dimensional domain wall…
On the quantum Poincare' group
Leonardo Castellani
The inhomogeneous quantum groups are obtained by means of a particular projection of . The bicovariant differential calculus on is likewise projecte…
