We also consider the related class where Dirac delta functions are allowed. We prove several results on the boundary behavior of functions of two variables F(x,y), x ∈ ℝ, y>0, with F(x,0⁺) = f(x) distributionally, both near points where the distributional point value exists and points where the lateral distributional limits exist.

We also characterize the Fourier transforms of tempered distributionally regulated functions in two ways.
