On the effective reduction of an ideal

Tomasz Rodak, Adam Różycki, Stanisław Spodzieja

It is well known that in the Noetherian local ring with infinite residue field the reduction of $\mm$-primary ideal may be given in the form of a sufficiently general linear combin…

Effective Bertini theorem and formulas for multiplicity and the local Łojasiewicz exponent

Tomasz Rodak, Adam Różycki, Stanisław Spodzieja

The classical Bertini theorem on generic intersection of an algebraic set with hyperplanes states the following: \emph{Let X be a nonsingular closed subvariety of ,…

Effective Łojasiewicz gradient inequality and finite determinacy of non-isolated Nash function singularities

Beata Osińska-Ulrych, Grzegorz Skalski, Stanisław Spodzieja

Let be a compact semialgebraic set and let be a nonzero Nash function. We give a Solernó and D'Acunto-Kurdyka type estimation of the exp…

Exponential convexifying of polynomials

Krzysztof Kurdyka, Katarzyna Kuta, Stanisław Spodzieja

Let be a convex closed and semialgebraic set and let be a polynomial positive on . We prove that there exists an exponent , such that for any…

A geometric model of an arbitrary differentially closed field of characteristic zero

Stanisław Spodzieja

We give an elementary construction of an arbitrary differentially closed field and of a universal differential extension of a differential field in terms of Nash function fields. W…

Sufficiency of non-isolated singularities

Piotr Migus, Tomasz Rodak, Stanisław Spodzieja

We give, in terms of the Łojasiewicz inequality, a sufficient condition for -mappings germs of non-isolated singularity at zero to be isotopical.
