Are all identically conserved geometric tensors metric variations of actions? A status report
/ Deser, S. ; Pang, Y.
Noether's theorem, that local gauge variations of gauge invariant actions are identically conserved (more tautologically, that gauge variations of gauge invariants vanish) was established a century ago. [...]

NonLagrangian gauge field models are physically excluded
/ Deser, S.
While nonactiongenerated, but identically conserved, abelian/YM gauge vectors exist, they are unsuitable for building alternate field equations, because they have no stresstensor, hence do not permit Poincare generators and, most physically, cannot consistently couple to gravity. [...]

Propagation peculiarities of mean field massive gravity
/ Deser, S. ; Waldron, A. ; Zahariade, G.
Massive gravity (mGR) describes a dynamical “metric” on a fiducial, background one. [...]

Duality invariance of s≥32 fermions in AdS
/ Deser, S. ; Seminara, D.
We show that in D=4 AdS, s≥3/2 partially massless (PM) fermions retain the duality invariances of their flat space massless counterparts. [...]
