Notes

Kakeya set is being defined in a rotational invariant way, so it should have some rotational symmetric properties. In fact, a certain rotational invariance of Kakeya set implies the Kakeya conjecture.

In this note, we prove one of Furstenberg's results on times 2, times 3 theorem for closed invariant sets
