Free arrangements of hyperplanes have remarkable properties like the factorization of their characterictic polynomials. There is a long unsettled conjecture about the combinatorial nature of the freeness. This talk discusses classical results concerning reflection arrangements, fiber-type arrangements, and logarithmic differential forms as well as some recent progress.
