The projective transformations of n-dimensional space give rise to a one-parameter family of inhomogeneous first-order differential operator representations of sln+1. By restricting to the subalgebra on+1, we obtain new explicit representations for the simple Lie algebras of type B or type D. Applying these operators on the space of exponential-polynomial functions or partially swapping differential operators and multiplication operators, we realize more general explicit representations for on+1. All of these representation spaces are infinite-dimensional. We obtain the composition series of these on+1-modules under certain conditions.
