Bloom-type two-weight inequalities for commutators of maximal functions

Analysis and Geometry in Metric Spaces
We study Bloom-type two-weight inequalities for commutators of the Hardy-Littlewood maximal function and sharp maximal function. Some necessary and sufficient conditions are given to characterize the two-weight inequalities for such commutators.

Spatially Periodic Solutions for Evolution Anisotropic Variable‐Coefficient Navier–Stokes Equations: II. Serrin‐Type Solutions

Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 11592-11619, August 2025.
ABSTRACT We consider evolution (nonstationary) space‐periodic solutions to the n$$ n $$‐dimensional nonlinear Navier–Stokes equations of anisotropic fluids with the viscosity coefficient tensor variable in space and time and satisfying the relaxed ellipticity condition.

Periodic Orbits of MAX and MIN Multistate Networks

Mathematical Methods in the Applied Sciences, Volume 48, Issue 12, Page 11620-11629, August 2025.
ABSTRACT This work presents a generalization of Boolean networks to multistate networks over a complement‐closed set 𝒞, which can be finite or infinite. Specifically, we focus on MAX (and MIN) multistate networks, whose dynamics are governed by global arbitrary 𝒞‐maxterm (or 𝒞‐minterm) functions, which extend the well‐known maxterm (or minterm) Boolean

K‐stable Fano threefolds of rank 2 and degree 28

Journal of the London Mathematical Society, Volume 112, Issue 2, August 2025.
Abstract Moduli spaces of Fano varieties have historically been difficult to construct. However, recent work has shown that smooth K‐polystable Fano varieties of fixed dimension and volume can be parametrised by a quasi‐projective moduli space. In this paper, we prove that all smooth Fano threefolds with Picard rank 2 and degree 28 are K‐polystable ...

Birational complexity and dual complexes

Proceedings of the London Mathematical Society, Volume 131, Issue 2, August 2025.
Abstract We introduce the notion of birational complexity of a log Calabi–Yau pair. This invariant measures how far the log Calabi–Yau pair is from being birational to a toric pair. We study fundamental properties of the new invariant, with a particular focus on the geometry of dual complexes.
