SUMMARY:Spin frames vs spin structures: A framework for Dirac fields in\nin
 teraction with gravity
CLASS:PUBLIC
DESCRIPTION:LORENZO FATIBENE\, UNIVERSITY OF TORINO\n\nWe relax spin struct
 ures to discuss Dirac fields in interaction with\ngravity and their conse
 rvation laws. That is an example of a more\ngeneral framework\, called ga
 uge natural field theories\, which\naccommodates theories which are genera
 lly covariant and they have an\nadditional gauge symmetry. The framework 
 is geometrically expressed\nand it accommodates a geometric formulation of
  both variational\ncalculus and conservation laws. We shall also briefl
 y compare with\nother frameworks such as the double cover of frame bundles
