摘要：
We show the existence of locally bounded global solutions to the chemotaxis system {u(t) = del.((u)del u) - del.(u/v del v) in Omega x(0, infinity) v(t) = Delta v - uv in Omega x(0, infinity) partial derivative v(u) = partial derivative(v)v = 0 in Omega x(0, infinity) u(., 0) = u(0,) v(., 0) = v(0) in Omega in smooth bounded domains Omega subset of R-N, N >= 2, for D(u) >= delta Um-1 with some delta > 0, provided that m > 1+ N/4.
