An Introduction to Jetbundles

In deformation theory certain problems can be solved by surprisingly simple and analytical means. Consider the following problem:

Given complex manifolds X and Y with holomorphic map f : Y -> X, does a first order infinitesimal deformation of f, a given section σ : Y -> f*TX, belong to a deformation of f? If so,  σ is called e ffective.

A special class of fi brebundles, so called Jetbundles are a very useful tool in this discussion. They generalise the notion of the tangent bundle of a manifold. Jetbundles can be used to prove a cohomological criterion for the effectiveness of fi rst order in finitesimal deformations.

In this talk the underlying problem will be explained and an analytic defi nition of Jetbundles will be given and used for a constructive approach to this abstract problem.

 

The talk is open to the public. Guests are cordially invited!
