Summary: An abstract causal operator equation y=Ay defined on a space of the form $$ \varepsilon(D_0^{\alpha}y_{\varepsilon})(t) =-y_{\varepsilon}(t)+(Ay_{\varepsilon})(t), \quad t\in[0,\tau], $$ where $D_0^{\alpha}$ denotes the (left) Riemann-Liouville derivative of order $\alpha\in(0,1)$. The main procedure lies on properties of the Mittag-Leffler function combined with some facts from convolution theory. Our results complete relative ones that have appeared in the literature; see, e.g. [5] in which regularization via ordinary differential equations is used.
