A correlation between the compton wavelength and the de Broglie wavelength

It is pointed out that the Compton wavelength λ _C plays the same role in relation to matter-waves in 4-dimensional space as does the de Broglie wavelength λ _D with respect to matter-waves in 3-dimensional space. In fact, it has been shown that λ _C is the 4-dimensional-space analog of λ _D (which is defined in 3-dimensional space). Implications of this correlation are also discussed.
