Query: Two-dimensional individual clustering model   This paper is devoted to study a model of individual clustering with two
specific reproduction rates in two space dimensions. Given q > 2 and an initial
condition in W 1,q (\Omega), the local existence and uniqueness of solution
have been shown in [6]. In this paper we give a detailed proof of existence of
global solution.
