CHERN CLASSES OF BIRATIONAL VARIETIES
, 2008 . Let ϕ: V W be a birational map between smooth algebraic varieties which does not change the canonical class (in the sense of Batyrev, [Bat99]). We prove that the total homology Chern classes of V and W are push-forwards of the same class from a ...

Classification of elliptic and K3 fibrations birational to some Q-Fano 3-folds
, 2006 A complete classification is presented of elliptic and K3 fibrations birational to certain mildly singular complex Fano 3-folds. Detailed proofs are given for one example case, namely that of a general hypersurface $X$ of degree 30 in weighted $\PP^4 ...

Lie symmetries of birational maps preserving genus 0 fibrations
, 2021 We prove that any planar birational integrable map, which preserves a fibration given by genus 0 curves has a Lie symmetry and some associated invariant measures.

Iterative properties of birational rowmotion II: Rectangles and triangles
, 2015 Birational rowmotion — a birational map associated to any finite poset P — has been introduced by Einstein and Propp as a far-reaching generalization of the (well-studied) classical rowmotion map on the set of order ideals of P.

Iterative Properties of Birational Rowmotion I: Generalities and Skeletal Posets
, 2014 We study a birational map associated to any finite poset P. This map is a far-reaching generalization (found by Einstein and Propp) of classical rowmotion, which is a certain permutation of the set of order ideals of P.
