Abstract
In this paper, we completely solve the extension conjecture for the zero radius sphere over finite fields. We also obtain the sharp extension estimate for non-zero radii spheres over finite fields, which improves the previous result of the first and second authors significantly. © Canadian Mathematical Society 2020.
