Unified Asymptotics for Investment Under Illiquidity: Transaction Costs and Search Frictions
Mathematical Finance, Volume 36, Issue 1, Page 67-98, January 2026.ABSTRACT This paper investigates the optimal investment problem in a market with two types of illiquidity: transaction costs and search frictions. We analyze a power‐utility maximization problem where an investor encounters proportional transaction costs and trades only when a Poisson process triggers trading opportunities.

A Design of an Axisymmetric Roof With a Horizontal Rotation Axis
Studies in Applied Mathematics, Volume 156, Issue 1, January 2026.ABSTRACT This research proposes a novel roof design whose shape follows the mathematical model of an ideal hanging surface. The resulting roof is a surface of revolution, but its rotation axis is horizontal, which challenges conventional intuition because the axis is perpendicular to the direction of gravity.

The GJMS operators in geometry, analysis and physics
Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.Abstract The GJMS operators, introduced by Graham, Jenne, Mason and Sparling, are a family of conformally invariant linear differential operators with leading term a power of the Laplacian. These operators and their method of construction have had a major impact in geometry, analysis and physics.

A theorem concerning Fourier transforms: A survey
Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.Abstract In this note, we highlight the impact of the paper G. H. Hardy, A theorem concerning Fourier transforms, J. Lond. Math. Soc. (1) 8 (1933), 227–231 in the community of harmonic analysis in the last 90 years, reviewing, on one hand, the direct generalizations of the main results and, on the other hand, the different connections to related areas ...
