Faraday effect: A field theoretical point of view

Star products: a group-theoretical point of view

Adopting a purely group-theoretical point of view, we consider the star product of functions which is associated, in a natural way, with a square integrable (in general, projective) representation of a locally compact group. Next, we show that for this (implicitly defined) star product explicit formulae can be provided. Two significant examples are studied in detail: the group of translations o...

Reformulating Planning Problems: A Theoretical Point of View

Automated planning is a well studied research topic thanks to its wide range of real-world applications. Despite significant progress in this area many planning problems still remain hard and challenging. Some techniques such as learning macro-operators improve the planning process by reformulating the (original) planning problem. While many encouraging practical results have been derived from ...

Abelian Sandpile Model: a Conformal Field Theory Point of View

In this paper we derive the scaling fields in c = −2 conformal field theory associated with weakly allowed clusters in abelian sandpile model and show a direct relation between the two models.

Noncommutative field theories from a deforma - tion point of view

In this review we discuss the global geometry of noncommutative field theories from a deformation point of view: The space-times under consideration are deformations of classical space-time manifolds using star products. Then matter fields are encoded in deformation quantizations of vector bundles over the classical space-time. For gauge theories we establish a notion of deformation quantizatio...
