The Polynomial-Time Low-Degree Conjecture is False

Songtao Mao

The polynomial-time low-degree conjecture, which predicts that low-degree indistinguishability, a uniform null distribution, permutation invariance, and independent resampling imply polynomial-time ha…

Oddomorphisms, Split-Off Minors, and the Strong Roberson Conjecture

Arnar Á. Kristjánsson

The paper shows that an oddomorphism between graphs does not imply graph minor containment and introduces a new structural relation called split-off minor.

Parity families and a kernel-averaged L-function for near-Ramanujan signings

Vaibhav Suvagiya

The paper studies the affine family of signings for a d-regular graph and shows that averaging over it converts the sign problem of the Bilu-Linial conjecture into a counting problem, proving matched…

Cut-homotopies and the complexity of edge-coloring problems

Alexey Barsukov, Roman Feller, Maximilian Hadek, Davide Perinti

The paper shows that every problem asking if a given graph has an edge-coloring without an edge-colored clique from a fixed family is poly-time equivalent to a Constraint Satisfaction Problem, resulti…

Conjectural Decidability of the Skolem Problem

Florian Luca, Joël Ouaknine, James Worrell

This paper introduces the concept of 'large' zeros in linear recurrence sequences and establishes that they either do not exist or are very sparse, which could lead to decidability of the Skolem Probl…

Recursive Jump Operators and Optimal Proof Systems

Fabian Egidy

The paper investigates the relationship between optimal proof systems and recursive jump operators, showing that while the existence of a jump operator rules out optimality, the converse is provably h…

An Enigma of Artificial Reason: Investigating the Production-Evaluation Gap in Large Reasoning Models

Mingzhong Sun, Teresa Yeo, Armando Solar-Lezama, Tan Zhi-Xuan

This paper investigates the production-evaluation gap in Large Reasoning Models (LRMs), finding that while LRMs excel at generating solutions, they struggle significantly to evaluate flawed reasoning,…
