The Dirichlet problem is studied for a one-dimensional isotropic superdiffusion equation of order $\alpha\in(1;2)$ on the semiaxis. The analytic solutions of this problem are obtained by the mapping method in the classes of continuous Hўоlder functions, which may have an integrable singularity with respect to time. The probability interpretation of the solutions is clarified and the uniqueness of the regular solution is proved on an infinite time interval. |
