Query: Dynamics of distributed sources   The dynamics of distributed sources is described by nonlinear partial
differential equations. Lagrangian analytical solutions of these (and
associated) equations are obtained and discussed in the context of Lagrangian
modeling - from the Lagrangian invariants to dynamics. Possible applications of
distributed sources and sinks to geophysical fluid dynamics and to the
cosmology are indicated.
