We show that if uis a Leray solution to the Navier–Stokes equations in the full three-dimensional space with an initial condition from W1,2 0,σ, T>0and u ∈Lt (0, T; Ls), where 2/t +3/s =59/30for s ∈(2, 30/13]and 2/t +3/s =7/4 +1/(2s)for s ∈(30/13, 3)then uis regular on (0, T). We prove our result as a special case of a more general method which might possibly bring a further improvement.
