Abstract: | Traditionally symmetries of field theories are encoded via Lie group actions, or more generally, as Lie algebra actions.
A significant generalization is required when “gauge parameters” act in a field dependent way. Such symmetries appear in several
field theories, most notably in a “Poisson induced” class due to Schaller and Strobl SS94] and to Ikeda Ike94], and employed
by Cattaneo and Felder CF99] to implement Kontsevich's deformation quantization Kon97]. Consideration of “particles of spin
> 2” led Berends, Burgers and van Dam Bur85,BBvD84,BBvD85] to study “field dependent parameters” in a setting permitting
an analysis in terms of smooth functions. Having recognized the resulting structure as that of an sh-Lie algebra (L
∞-algebra), we have now formulated such structures entirely algebraically and applied it to a more general class of theories
with field dependent symmetries.
