Abstract
In this paper we prove the following results in the plane. They are related other, while each of them has its own interest. First we obtain a nontrivial exponent on intersection between pencils of δ-tubes, undconcentration conditions. In fact we show it is equivalent to the discretized sum-product proThen we use our estimates of pencils to prove new results on dimensions of radial projeWe also make a conjecture that would reveal a key difference between orthogonal projectioradial projections.
