I discuss gauge theories for commutative but non-associative algebras
related to the SO(2k+1) covariant finite dimensional fuzzy 2k-sphere
algebras. A consequence of non-associativity is that gauge fields and
gauge parameters have to be generalized to be functions of coordinates as
well as derivatives. The usual gauge fields depending on coordinates only
are recovered after a partial gauge fixing.The deformation parameter for
these commutative but non-associative algebras is a scalar of the rotation
group. This suggests interesting string-inspired algebraic deformations of
spacetime which preserve Lorentz-invariance.
The talk will be based on hepth/0310153
