Abstract
We consider an incidence problem in which asks, for a set of lines and a set of planes in general position, what the maximum number of line-plane incidences is. A line-plane incidence is defined as a point where a line and a plane intersect. We prove that, when the lines and planes are in a truly 4-dimensional configuration such that no more than lines are contained in any 2-dimensional surface of degree at most and no more than 2-planes are contained in any 3-dimensional hypersurface of degree at most , and if , then for a constant and an there exists a non-trivial upper bound for incidences between lines and planes: . We also prove several supporting lemmas.
