Tail Criteria, No-Go Audits, and Apéry-Type Certificate Obstructions for the Irrationality of e+\pi

This paper investigates the open problem of the irrationality of e+πe+\pi by establishing exact arithmetic equivalences for its hypothetical rationality and conducting a comprehensive "no-go" audit of low-complexity Apéry-type proof mechanisms, ultimately demonstrating that within tested families, analytic smallness is consistently obstructed by denominator growth and continued-fraction shadows.

The MM-matrix group inverse problem for recoverable complete networks

This paper establishes necessary and sufficient conditions for the group inverse of a specific class of singular, irreducible, symmetric MM-matrices—motivated by recoverable complete networks—to retain the MM-matrix property, utilizing both matrix-theoretic methods and network potential theory to construct such matrices and deepen the link between MM-matrix theory and network analysis.

New lower bounds for the degree/diameter problem via interaction with a browser-accessible LLM

This paper presents new lower bounds for the degree/diameter problem, specifically N(12,5)34,992N(12,5)\ge 34{,}992 and N(16,5)147,456N(16,5)\ge 147{,}456, achieved through a novel discovery process where the author interacted directly with a standard web-accessible LLM to construct explicit graphs without using custom agent frameworks or pre-defined search strategies.

A lattice-theoretic framework for hesitant fuzzy convexity beyond scalar observables

This paper establishes a lattice-theoretic framework for convexity that separates domain segment structures from codomain lattice structures to demonstrate that symmetric hesitant fuzzy convexity cannot be fully reconstructed by any finite family of scalar observables, thereby revealing the limitations of scalar reductions in preserving intrinsic order-theoretic information.

Multicriticality and Scaling: Mellin Spectral Theory, and the Decoupling of Geometric and Spectral Exponents

This paper develops a spectral theory for scale-invariant operators on the multiplicative half-line using Mellin transforms to demonstrate that geometric and spectral exponents are fundamentally decoupled, providing a precise mathematical characterization of multicriticality where their inequality signals multiple independent scaling dimensions.
