Analytic Nullstellensätze and the model theory of valued fields

open access: yesMathematische Nachrichten, Volume 297, Issue 8, Page 2873-2917, August 2024.
Abstract We present a uniform framework for establishing Nullstellensätze for power series rings using quantifier elimination results for valued fields. As an application, we obtain Nullstellensätze for p$p$‐adic power series (both formal and convergent) analogous to Rückert's complex and Risler's real Nullstellensatz, as well as a p$p$‐adic analytic ...

Blocking sets, minimal codes and trifferent codes

open access: yesJournal of the London Mathematical Society, Volume 109, Issue 6, June 2024.
Abstract We prove new upper bounds on the smallest size of affine blocking sets, that is, sets of points in a finite affine space that intersect every affine subspace of a fixed codimension. We show an equivalence between affine blocking sets with respect to codimension‐2 subspaces that are generated by taking a union of lines through the origin, and ...

Combinatorial Nullstellensatz Modulo Prime Powers and the Parity Argument [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2014
We present new generalizations of Olson's theorem and of a consequence of Alon's Combinatorial Nullstellensatz. These enable us to extend some of their combinatorial applications with conditions modulo primes to conditions modulo prime powers. We analyze computational search problems corresponding to these kinds of combinatorial questions and we prove ...

Combinatorial Nullstellensatz approach to polynomial expansion

open access: yesActa Arithmetica, 2014
Applying techniques similar to Combinatorial Nullstellensatz we prove a lower estimate of $|f(A,B)|$ for finite subsets $A$, $B$ of a field, and polynomial $f(x,y)$ of the form $f(x,y)=g(x)+yh(x)$, where degree of $g$ is greater then degree of $h$.

Combinatorial Nullstellensatz Techniques

open access: yesCoRR
We present different techniques for applying Combinatorial Nullstellensatz to polynomials over finite fields. For examples, we generalize theorems from Noga Alon's paper on the subject, and present a few of our own.

Proof of the Combinatorial Nullstellensatz over Integral Domains, in the Spirit of Kouba [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2010
It is shown that by eliminating duality theory of vector spaces from a recent proof of Kouba [A duality based proof of the Combinatorial Nullstellensatz, Electron. J. Combin. 16 (2009), #N9] one obtains a direct proof of the nonvanishing-version of Alon's Combinatorial Nullstellensatz for polynomials over an arbitrary integral domain.

Computing infeasibility certificates for combinatorial problems through Hilbert’s Nullstellensatz

open access: yesJournal of Symbolic Computation, 2011
Systems of polynomial equations over a field can yield compact models of difficult combinatorial problems and they can be used to prove combinatorial results. In particular, existence of the solutions of the systems means that the combinatorial objects have the properties captured by the systems.

Quantitative Combinatorial Nullstellensatz

open access: yes, 2012
The main result of this paper is a coefficient formula that sharpens and generalizes Alon and Tarsi's Combinatorial Nullstellensatz, which provides some information about the polynomial map $P|_{\X_1\times...\times\X_n}$ when only incomplete information about the polynomial $P(X_1,...c,X_n)$ is given. In a very general working frame, the grid points $x\
