Remarks on the degree growth of birational transformations

Christian Urech

We look at sequences of positive integers that can be realized as degree sequences of iterates of rational dominant maps of smooth projective varieties over arbitrary fields. New c…

On homomorphisms between Cremona groups

Christian Urech

We look at algebraic embeddings of the Cremona group in $n$ variables $C r_{n} (C)$ to the group of birational transformations $B i r (M)$ of an algebraic variety $M$ . First we study geom…
