Spectral pseudorandomness and the road to improved clique number bounds for Paley graphs

D Kunisky - Experimental Mathematics, 2024 - Taylor & Francis
We study subgraphs of Paley graphs of prime order p induced on the sets of vertices
extending a given independent set of size a to a larger independent set. Using a sufficient …

Igusa's conjecture for exponential sums: optimal estimates for nonrational singularities

R Cluckers, M Mustaţă, KH Nguyen - Forum of Mathematics, Pi, 2019 - cambridge.org
We prove an upper bound on the log canonical threshold of a hypersurface that satisfies a
certain power condition and use it to prove several generalizations of Igusa's conjecture on …

Arithmetic progressions in certain subsets of finite fields

S Eyidoğan, H Göral, MK Kutlu - Finite Fields and Their Applications, 2023 - Elsevier
In this note, we focus on how many arithmetic progressions we have in certain subsets of
finite fields. For this purpose, we consider the sets S p={t 2: t∈ F p} and C p={t 3: t∈ F p} …

Mutual position of two smooth quadrics over finite fields

S Asgarli, CH Yip - arXiv preprint arXiv:2404.06754, 2024 - arxiv.org
Given two irreducible conics $ C $ and $ D $ over a finite field $\mathbb {F} _q $ with $ q $
odd, we show that there are $ q^ 2/4+ O (q^{3/2}) $ points $ P $ in $\mathbb {P}^ 2 (\mathbb …

Geometric generalizations of the square sieve, with an application to cyclic covers

A Bucur, AC Cojocaru, MN Lalín, LB Pierce - Mathematika, 2023 - Wiley Online Library
We formulate a general problem: Given projective schemes YY and XX over a global field K
and a K‐morphism η from YY to XX of finite degree, how many points in X (K) X(K) of height …

Discriminants of fields generated by polynomials of given height

R Dietmann, A Ostafe, IE Shparlinski - arXiv preprint arXiv:1909.00135, 2019 - arxiv.org
We obtain upper bounds for the number of monic irreducible polynomials over $\mathbb Z $
of a fixed degree $ n $ and a growing height $ H $ for which the field generated by one of its …

On a conjecture of Wooley and lower bounds for cubic hypersurfaces

VV Kumaraswamy, N Rome - arXiv preprint arXiv:2405.04234, 2024 - arxiv.org
Let $ X\subset\mathbf {P} _ {\mathbf {Q}}^{n-1} $ be a cubic hypersurface cut out by the
vanishing of a non-degenerate rational cubic form in $ n $ variables. Let $ N (X, B) $ denote …

Stratification for multiplicative character sums

J Xu - International Mathematics Research Notices, 2020 - academic.oup.com
We prove a stratification result for certain families of n-dimensional (complete algebraic)
multiplicative character sums. The character sums we consider are sums of products of r …
