The rationality problem for conic bundles
arXiv:1712.05564 · doi:10.1070/RM9811
Abstract
This expository paper is concerned with the rationality problems for three-dimensional algebraic varieties with a conic bundle structure. We discuss the main methods of this theory. We sketch the proofs of certain principal results, and present some recent achievements. Many open problems are also stated.
