Outline of Final Research Achievements

We proved the uniqueness of bounded continuous L_{3,weak}-solutions on the whole time axis to the Navier-Stokes equations in 3-dimensional unbounded domains. Here, L_{3,weak} denotes the weak L_3 space. Thus far, uniqueness of such solutions to the Navier-Stokes equations in unbounded domain, roughly speaking, is known only for a small solution in BC(R;L_{3,weak}) within the class of solutions which have sufficiently small BC(R; L_{3,weak})-norm. In this study, we established another type of uniqueness theorem for solutions in BC(R;L_{3,weak}) using a smallness condition for one solution and a precompact range condition for the other one.
