Abstract: Uniform local energy estimates were used by Jia and Sverak to prove the existence of self-similar solutions of the Navier-Stokes equations associated to a regular homogeneous initial value; their result is easily extended to the case of rough initial values (only locally L^2 and homogeneous). The case of discretely self-similar solutions was then solved by Bradshaw and Tsai, and by Chae and Wolf. We propose (my Ph.D. student and I) a simple proof by using weighted energy estimates.
