Resumen
In this paper, we establish some density theorems in the setting of particular locally convex vector lattices of continuous functions defined on a locally compact Hausdorff space, which we introduced and studied in [3, 4] and which we named regular vector lattices. In this framework, by using properties of the subspace of the socalled generalized affine functions, we give a simple description of the closed vector sublattice, the closed Stone vector sublattice and the closed subalgebra generated by a subset of a regular vector lattice.
As a consequence, we obtain some density results. Finally, a connection with the Korovkin type approximation theory is also shown.
