Аннотация:We prove the global weak solvability of the problem on a flow of an ideal incompressible
fluid in a domain containing various types of sources and sinks. In the first part of the paper
the case of point sources and sinks is considered. This situation is characterized by singularities
of the velocity vector field, whose second powers are not integrable. We suggest a new generalized
formulation of the problem, where the singularities are described by corresponding measures. As
a development of this technique, we solve in the second part of the paper the problem on a flow
of an ideal fluid through a given domain.
