We present some obvious physical requirements on gravitational avatars of non-linear elec-trodynamics and illustrate them with explicit determinantal Born–Infeld–Einstein models. A related procedure, using compensating Weyl scalars, permits us to formulate conformally invariant versions of these systems as well. Born–Infeld (BI) electrodynamics [1] has earned its longevity through its elegant, ...

We construct a class of representations of the quadratic R-matrix algebra given by the reflection equation with the spectral parameter, R (u − v)T (u)R (u + v)T (v) = T (v)R (u + v)T (u)R (u − v), in terms of certain ordinary difference operators. These operators turn out to act as parameter shifting operators on the 3F 2(1) hypergeometric function and its limit cases and on classical orthogona...
