Birational Quadratic Planar Maps with Generalized Complex Rational Representations

open access: yesMathematics, 2023
Complex rational maps have been used to construct birational quadratic maps based on two special syzygies of degree one. Similar to complex rational curves, rational curves over generalized complex numbers have also been constructed by substituting the ...

On the monomial birational maps of the projective space [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2003
We describe the group structure of monomial Cremona transformations. It follows that every element of this group is a product of quadratic monomial transformations, and geometric descriptions in terms of fans.

Motivic invariants of birational maps

open access: yesAnnals of Mathematics
We construct invariants of birational maps with values in the Kontsevich--Tschinkel group and in the truncated Grothendieck groups of varieties. These invariants are morphisms of groupoids and are well-suited to investigating the structure of the Grothendieck ring and L-equivalence.

On Birational Maps and Jacobian Matrices [PDF]

open access: yesCompositio Mathematica, 2001
One is concerned with Cremona-like transformations, i.e., rational maps from $ P$ n to $ P$ m that are birational onto the ...

On degrees of birational mappings [PDF]

open access: yesMathematical Research Letters, 2020
We prove that the degrees of the iterates ${\rm deg}(f^n)$ of a birational map satisfy $\liminf({\rm deg}(f^n))

Torification and factorization of birational maps [PDF]

open access: yesJournal of the American Mathematical Society, 2002
Building on work of the fourth author and Morelli’s work, we prove the weak factorization conjecture for birational maps in characteristic zero: a birational map between complete nonsingular varieties over an algebraically closed field K
