Geometric desingularization of curves in manifolds
(Wydawnictwo Uniwersytetu Łódzkiego, 2013) -
Rings of constants of polynomial derivations and p-bases
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)We present a survey of results concerning p-bases of rings of constants with respect to polynomial derivations in characteristic p > 0. We discuss characterizations of rings of constants, properties of their generators and ... -
On smooth hypersurfaces containing a given subvariety
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)We reprove some results about affine complete intersections. -
Introduction to the local theory of plane algebraic curves
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)We consider the algebroid plane curves de ned by formal power series of two variables with coe cients in an algebraically closed eld. Using quadratic transformations we prove the local normalization theorem. Then we study ... -
Multiple zeta values and the WKB method
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)The multiple zeta values ζ(d1, . . . , dr ) are natural generalizations of the values ζ(d) of the Riemann zeta functions at integers d. They have many applications, e.g. in knot theory and in quantum physics. It turns ... -
On Chouikha’s isochronicity criterion
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)Recently A.R.Chouikha gave a new characterization of isochronicity of center at the origin for the equation x'' + g(x) = 0, where g is a real smooth function de_ned in some neighborhood of 0 ϵ R. We present some new ... -
On rings of Darboux-like functions. From questions about the existence to discrete dynamical systems
(Wydawnictwo Uniwersytetu Łódzkiego, 2013) -
On C0-sufficiency of jets
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)The paper presents some details of the proofs by Kuiper and Kuo, and Bochnak and Łojasiewicz that refer to the impact of the Łojasiewicz exponent of gradient mappings on C0-sufficiency of jets. -
On combinatorial criteria for isolated singularities
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)In this article we review combinatorial characterizations of isolated singularities. As a new result in two and three-dimensional case we give sufficient and necessary conditions for a nondegenerate singularity to be ... -

Necessary conditions for irreducibility of algebroid plane curves
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)Let K be an algebraically closed field of characteristic 0 and let ƒ ϵ K[[X]] [Y] be monic. Using the properties of approximate roots given in [J. Algebra 343 (2011), pp. 143-159] we propose some necessary conditions for ... -
