On the set of fixed points of a polynomial automorphism
Zbigniew Jelonek, Tomasz Lenarcik
Let K be an algebraically closed field of characteristic zero. We say that a polynomial automorphism f : K^n -> K^n is special if the Jacobian of f is equal to 1. We show that ever…

Linear systems over P1xP1 with base points of multiplicity bounded by three
Tomasz Lenarcik
We propose a combinatorial method of proving non-specialty of a linear system of curves with multiple points in general positions. As an application we obtain a classification of s…
