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 ...

State Determination and Sufficiency of Observables
(Springer, 2013-05-19)
Informational completeness and the possibility of state distinction and determination are among the more important issues of quantum statistics. We use spectral and semispectral (POV) measures to analyse these questions. ...
