Algebraic L[sup 2] decay for the solution to a class system of non-Newtonian fluid in R[sup n].

In this paper, we investigate the L[sup 2] decay rates for the solution to a class system of non-Newtonian fluid in R[sup n](n>=2). The decay rates are optimal in the sense that they coincide with the decay rates of the solution to the heat system. © 2000 American Institute of Physics. [ABSTRACT FROM AUTHOR]
