A model for normed algebras in rational G-spectra

Giorgi Tigilauri · 2026

For a finite group $G$, we construct a simplified model for the $G$-symmetric monoidal $G$-$\infty$-category of rational $G$-spectra. Using this model, we classify $\mathcal{I}$-normed algebras in rat…

On nonnegative solutions of the parabolic differential inequality with $(p,q)$-Laplace on Riemannian manifolds

Biqiang Zhao · 2026

In this paper, we establish Liouville-type theorems for parabolic differential inequalities with $(p,q)-$Laplacian operator on Riemannian manifolds. By a test function argument, we establish nonexiste…

Trilinear Kloosterman fractions I: partially fixed moduli and unbalanced convolutions

Thomas Wright · 2026

In this paper, we improve on Fouvry and Radziwi{\l}{\l}'s results on unbalanced convolutions. In particular, we find that if $(\alpha_m)$ and $(\beta_n)$ are sequences supported on $m\sim M$ and $n\si…
