DESCRIPTION:It will be shown that usual free field equations for massless 
 gauge fields have more global symmetries when formulated in a AdS-like cur
 ved symmetric space than in Minkowski space. In particular\, it will be sh
 own that\, although the conformal symmetry su(2\,2) admits no consistent l
 ocal realization in terms of spin s>1 gauge potentials in 4d Minkowski spa
 ce\, it can be defined in the AdS_4 background. Analogous phenomenon will 
 be shown to take place for the sp(8|R) symmetry of the infinite tower of m
 assless higher spin fields of all spins. Relevant properties of the first-
 order "unfolded dynamics" approach undelrying the construction will be dis
 cussed in some detail.\n\nhttps://indico.ific.uv.es/event/1530/
