Order-3 pi-formulas, Apery-like kernels, and Clausen functoriality for Conservative Matrix Fields

This paper unifies order-3 π\pi-formulas and Apery-like kernels within a rank-2 Conservative Matrix Field framework by proving they arise as shifted lifts of explicit order-2 kernels derived from Gauss-square coefficients and Domb numbers, while establishing a Sym2\operatorname{Sym}^2 functoriality that classifies these structures and generates 11 new integer sequences via Belyi pullbacks.

Cusp Form Dimensions, Lattice Uniqueness, and LP Sharpness for Sphere Packing in Dimensions 8 and 24

This paper investigates the unique sharpness of the Cohn-Elkies linear programming bound for sphere packing in dimensions 8 and 24 by analyzing three independent necessary conditions from number theory, lattice theory, and conformal field theory, ultimately proposing a conjecture that these conditions are equivalent for dimensions divisible by 8 and unified through the Bost-Connes quantum statistical system.

Algorithms on the Pyasetskii involution on local Langlands parameters of classical groups

This paper presents an algorithm for computing the Pyasetskii involution on local Langlands parameters for the classical groups Sp2n\mathrm{Sp}_{2n}, SO2n+1\mathrm{SO}_{2n+1}, and O2n\mathrm{O}_{2n} by combining Moeglin-Waldspurger's method for GLn\mathrm{GL}_n with Lanard-Mínguez's approach for Aubert-Zelevinsky involutions, while also providing a geometric interpretation for the bad parity case.

Pro-pp Iwahori-Hecke modules in semisimple rank one and singularity categories

This paper establishes an equivalence between the homotopy category of Hovey's Gorenstein projective model structure on pro-pp Iwahori-Hecke modules for semisimple rank one groups and the singularity category of an explicit scheme, thereby recovering Grosse-Klönne's mod-pp Langlands correspondence for GL2\mathrm{GL}_2 and providing a complete explicit description for SL2\mathrm{SL}_2 and PGL2\mathrm{PGL}_2.
