Continuous spin field in the AdS₆ space

A representation of the so(2,5) algebra corresponding to the continuous spin field in AdS₆ is considered. The algebra is realized using the Lie-Lorentz derivative, which naturally incorporates AdS₆ geometry and spin degrees of freedom. Within this framework, we derive explicit expressions for the Casimir operators in terms of both the covariant derivative and the spin invariants. The continuous spin representation under consideration is defined by a system of operator constraints that generalize those known for six-dimensional Minkowski space. We demonstrate that these constraints completely fix all Casimir operators of the so(2,5) algebra, with the eigenvalues determined by a dimensional real parameter μ and a positive (half-)integer s.
