WebPego type theorem has also been studied via the short-time Fourier and wavelet trans-forms [2], the Laplace transform [11] and the Laguerre and Hankel transforms [10]. The Pego theorem has been extended to the locally compact abelian groups with some tech-nical assumptions [5]. Using the Pontryagin duality and the Arzela-Ascoli theorem, the
