On a Weiss-type Almost Monotonicity Formula

Aelson Sobral · 2026

We establish a Weiss-type almost-monotonicity formula for a broad class of variable-coefficient energy functionals, assuming only minimal regularity of the coefficients. As an application, we classify…

Identification in (Endogenously) Nonlinear SVARs Is Easier Than You Think

James A. Duffy, Sophocles Mavroeidis · 2026

We study identification in structural vector autoregressions (SVARs) in which the endogenous variables enter nonlinearly on the left-hand side of the model, a feature we term endogenous nonlinearity, …

The two-phase Alt-Phillips problem for quasilinear operators

Yousef Alamri, Jose Miguel Urbano · 2026

We establish interior regularity and optimal growth estimates for sign-changing minimizers of the $p-$singular or $p-$degenerate quasilinear Alt--Phillips functional throughout the full range of $1<p<…

Verifying Well-Posedness of Linear PDEs using Convex Optimization

Declan S. Jagt, Matthew M. Peet · 2026

Ensuring that a PDE model is well-posed is a necessary precursor to any form of analysis, control, or numerical simulation. Although the Lumer-Phillips theorem provides necessary and sufficient condit…

Partial regularity for minimizing constraint maps for the Alt-Phillips energy

Rada Ziganshina · 2026

In this paper, we establish an $\varepsilon$-regularity theorem for minimizers of an Alt-Phillips type functional subject to constraint maps. We prove that under sufficiently small energy, the minimiz…

The Inflation of Resetting Workers

Rui Sun · 2026

The standard wage Phillips curve aggregates away from which workers reset wages when. I show this aggregation omits a first-order term: the covariance between workers' cost-push exposure and their res…

An Inflation Model for the Colombian Case. 2001 2025

Wilman Arturo Gomez, Carlos Esteban Posada · 2026

Since the beginning of this century the Colombian monetary authority has conducted monetary policy under a strategy based on setting targets for interest rate and inflation, while allowing the exchang…

Strong spectral gap for geometrically finite hyperbolic manifolds

Dubi Kelmer, Osama Khalil, Pratyush Sarkar · 2026

Let $\Gamma < G := \operatorname{SO}(d+1, 1)$ for $d \geq 1$ be a Zariski dense, geometrically finite, discrete subgroup with critical exponent strictly greater than $d/2$. We show that $L^2(\Gamma\ba…
