Abstract
A partial differential equation of fractional order with an arbitrary number of independent variables is studied. For integer orders of fractional derivatives, the equation under consideration becomes a second-order linear elliptic equation with Laplace operator in the principal part. The Dirichlet problem in a multidimensional domain is considered. The extremum principle for the equation under study and the uniqueness of the solution of the problem under consideration in a bounded or an unbounded domain are proved.
