In this paper, we prove the local existence and uniqueness of a moving boundary problem modeling chemotactic phenomena. We also get the explicit representative for the moving boundary and show the finite-time blow-up and chemotactic collapse for the solution of the problem.
Keywords: Moving boundary, blow-u, chemosensitive movement, chemotactic collapse..
