DESCRIPTION:Speakers: Janusz Grabowski\n\nWe discuss Jacobi sigma models f
 or general Jacobi structures understood as Jacobibundles\, i.e.\, Lie brac
 kets on sections of (possibly nontrivial) line bundles. A particular casei
 s that of contact manifolds.The construction is built on a canonical corre
 spondence between Jacobi bundles and homogeneousPoisson structures on prin
 cipal bundles with the structure group R^× = GL(1\;R).Consequently\, solu
 tions of the field equations are morphisms of certain Jacobi algebroids\, 
 i.e.\,principal R^×-bundles equipped additionally with a compatible Lie a
 lgebroid structure. Oursigma models are intrinsically geometric and fully 
 covariant.\n\nhttps://indico.math.cnrs.fr/event/14202/
