Uncertainty principle for the Riemann-Liouville operatorKeywords: Beurling-Hormander theorem , Gelfand-Shilov theorem , Cowling- Price theorem , Fourier transform , Riemann-Liouville operator Abstract: A Beurling-Hormander theorem's is proved for the Fourier transform connected with the Riemann-Liouville operator. Nextly, Gelfand-Shilov and Cowling-Price type theorems are established. Se demuestra el teorema de Beurling-Hormander por la transformada de Fourier conectada con el operador de Riemann-Liouville. Ademas, se establecen teoremas tipo de Gelfand-Shilov y Cowling-Price.
