Effective proof of Guseĭn-Zade theorem that branches may be deformed with jump one
(Wydawnictwo Uniwersytetu Łódzkiego, 2022)W pracy podajemy efektywny dowód twierdzenia Gusein-Zade, że osobliwe nierozkładalne lokalne krzywe płaskie (gałęzie) mogą być deformowane ze skokiem liczby Milnora równym jeden. W dowodzie korzystamy z wersji twierdzenia ... -
Entropy of Quantum Measurement
(MDPI, 2015-03-12)A notion of entropy of a normal state on a finite von Neumann algebra in Segal’s sense is considered, and its superadditivity is proven together with a necessary and sufficient condition for its additivity. Bounds on the ... -
Euclidean algorithm and polynomial equations after Labatie
(Wydawnictwo Uniwersytetu Łódzkiego, 2013)We recall Labatie's effective method of solving polynomial equations with two unknowns by using the Euclidean algorithm. -

Extremal properties of line arrangements in the complex projective plane
(Wydawnictwo Uniwersytetu Łódzkiego, 2019)In the present note we study some extreme properties of point-line configurations in the complex projective plane from a viewpoint of algebraic geometry. Using Hirzebruch-type inequalites we provide some new results on ... -
Finitely generated subrings of R[x]
(Wydawnictwo Uniwersytetu Łódzkiego, 2019)In this article all rings and algebras are commutative with identity, and we denote by R[x] the ring of polynomials over a ring R in one variable x. We describe rings R such that all subalgebras of R[x] are finitely generated ... -
Fixed points of dynamic processes of set-valued F-contractions and application to functional equations
(Springer International Publishing, 2015-02-11)The article is a continuation of the investigations concerning F-contractions which have been recently introduced in [Wardowski in Fixed Point Theory Appl. 2012:94,2012]. The authors extend the concept of F-contractive ... -
Formal and convergent solutions of analytic equations
(Łódź University Press, 2017)We provide the detailed proof of a sharpened version of the M. Artin Approximation Theorem. -
Gelfond-Mahler inequality for multipolynomial resultants
(Wydawnictwo Uniwersytetu Łódzkiego, 2019)We give a bound of the height of a multipolynomial resultant in terms of polynomial degrees, the resultant of which applies. Additionally we give a Gelfond-Mahler type bound of the height of homogeneous divisors of a ... -

Generalized gradients on Lie algebroids
(Springer Netherlands, 2013)Generalized O(n) -gradients for connections on Lie algebroids are derived. -

Hausdorff quasi-distances, periodic and fixed points for Nadler type set-valued contractions in quasi-gauge spaces
(Springer, 2014-12-05)In a quasi-gauge space (X,P) with quasi-gauge , using the left (right) -families of generalized quasi-pseudodistances on X (-families on X generalize quasi-gauge ), the left (right) quasi-distances DL−Jη ( DR−Jη) of Hausdorff ... -

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 ... -
