terrà un seminario dal titolo:

*“**How to define the symbol of a Fourier Integral Operator?**”*


In 1971, Hörmander introduced the Fourier Integral Operators associated to
homogeneous phase functions, and defined their principal  symbol as a
section of a line bundle (the Maslov bundle). However, this bundle,
abstractly defined via its transition functions, has no concrete meaning
and the definition is strictly linked to the homogeneity of the  phases. I
developed more recently an extended theory of Fourier Integral Operator
associated to non necessarily homogeneous canonical  transformations. In
that context,  their symbol  appears naturally as  sections of a more
concrete bundle, made of metaplectic operators. The comparison between the
two points of view, in the case of (almost)
homogeneous phase functions leads to a new construction of the Maslov bundle
and of  the symbols of FIO.

Tutti gli interessati sono invitati a partecipare.
