Classification of unions of >11 lines that are Cremona contractible
Insights into plane curve transformations
Abstract
We discuss the concept of Cremona contractible plane curves, with an historical account on the development of this subject. We then classify Cremona contractible unions of d > 11 lines in the plane.
