| Abstract: | Immigration
may rfluence the process of population development. In this paper, the solution of a kind
of partial differential equation on the human population mathemetial model with
immigration was discussed. The formula of solution for this equation are obtained by the
characteristic line method. The theorem on the global existance and uniqueness of
solutions for this equation are also theoritically proved. |
