(Wydawnictwo Uniwersytetu Łódzkiego, 2019)In the present note we investigate to which extent the configuration of 9 lines intersecting in triples in 12 points is determined by these incidences. We show that up to a projective automorphism there is exactly one such ...
(Wydawnictwo Uniwersytetu Łódzkiego, 2019)In the article the relation between irreducible curve plane singularities and knots is described. In these terms the topological classification of such singularities is given.
(Wydawnictwo Uniwersytetu Łódzkiego, 2019)In this paper we discuss an explicit form of divergence-free polynomial derivations in positive characteristic. It involves Jacobian derivations.
(Wydawnictwo Uniwersytetu Łódzkiego, 2019)The containment problem between symbolic and ordinary powers of homogeneous ideals has stimulated a lot of interesting research recently. In the most basic case of points in P2 and powers I(3) and I2, there is a number of ...
(Wydawnictwo Uniwersytetu Łódzkiego, 2019)We investigate properties of the contact exponent (in the sense of Hironaka [Hi]) of plane algebroid curve singularities over algebraically closed fields of arbitrary characteristic. We prove that the contact exponent is ...
